Key Facts
- Michigan state level: An arrest is a law-enforcement action, not a conviction or proof that a charged offense occurred.
- Michigan state level: Michigan Compiled Laws section 764.15 lists circumstances in which a peace officer may arrest a person without a warrant.
- Michigan state level: Michigan State Police criminal-history records can include felony arrests and convictions and specified misdemeanor information.
- Michigan state level: ICHAT, court records, and the Department of Corrections’ OTIS system answer different questions and do not contain the same information.
- Michigan state level: A missing online result does not establish that no arrest, case, nonpublic record, federal matter, out-of-state matter, or older correctional history exists.
The phrase “Michigan arrest” can describe both an event and a search for records about that event. Those are different subjects. Michigan law governs when officers may make arrests, while separate police, court, and corrections systems preserve different parts of what may happen afterward.
An arrest is not the same as a criminal conviction
An arrest means that legal authority has been used to take a person into custody. It does not itself decide guilt. A prosecutor’s charging decision, a court’s case record, and a conviction are later and legally distinct events.
This distinction matters when reading a Michigan criminal record. An arrest entry can appear without establishing that a court convicted the person of the suspected offense, and a record should be read together with any available charge and disposition information.
When Michigan officers may arrest without a warrant
Michigan Compiled Laws section 764.15 authorizes warrantless arrest in listed circumstances. They include an offense committed in the officer’s presence, a person who has committed a felony, and reasonable cause to believe that a felony was committed and that the person committed it.
The statute also covers reasonable cause concerning a felony or a misdemeanor punishable by more than 92 days, subject to its terms. Additional provisions address positive information that another peace officer holds a warrant and several specifically identified offenses or situations.
Section 764.15 is not a complete description of every arrest power or every procedural rule. A warrant-based arrest depends on the warrant and governing process, while other statutes address particular circumstances.
Michigan arrest records are distributed across systems
There is no single public screen that reproduces every record held by every Michigan justice agency. The useful starting point depends on whether the question concerns state criminal history, a court case, correctional supervision, or an underlying agency report.
ICHAT provides public Michigan State Police criminal-history information
The Michigan State Police describes a criminal-history record as including personal descriptors and information about misdemeanor convictions and felony arrests and convictions. Its Internet Criminal History Access Tool, known as ICHAT, provides name-based access to public criminal-history information maintained by the Criminal Justice Information Center.
MSP states that ICHAT does not provide suppressed records or warrant information. It also excludes federal, tribal, traffic, juvenile, out-of-state, and local-misdemeanor records described on the agency’s guidance page. A search result is therefore bounded by the repository and its public-access rules.
A separate Michigan background-check overview explains the distinction between name-based and fingerprint-based checks. MSP uses fingerprint procedures for specified authorized purposes and describes a personal-record process that can reveal public and nonpublic Michigan information associated with submitted fingerprints.
Court records show case activity and dispositions
Michigan Court Rule 8.119 governs access to court records. It treats case records as public subject to stated restrictions and permits courts to provide public case-history information through a publicly accessible website.
A court record can show filings, charges, hearings, and a disposition associated with a case. Access can still be restricted by statute, court rule, or a sealing order, and protected personal identifying information is not treated as ordinary public content.
OTIS is a corrections database, not a statewide arrest index
The Michigan Department of Corrections’ Offender Tracking Information System concerns people under MDOC jurisdiction. MDOC explains that OTIS includes prisoners, parolees, and probationers who are currently supervised or remain within the system’s stated post-discharge period.
MDOC also explains that most OTIS information comes from court records and that correction requests may involve the sentencing court or supervising office. Because OTIS focuses on correctional supervision, it should not be treated as a complete list of Michigan arrests.
Why an arrest record may be incomplete or absent online
Different omissions have different explanations. Information may belong to a local agency, a federal or tribal authority, another state, a court file, or a nonpublic portion of the state repository. An older corrections record may also fall outside OTIS’s public display period.
Suppression, sealing, or a conviction set-aside can also affect public visibility. MSP’s correction guidance distinguishes errors in arrest, charge, and court segments and directs each kind of correction to the agency responsible for the entry.
A public-record search is also different from an active arrest warrant inquiry. MSP expressly states that ICHAT does not provide warrant information, so a criminal-history search should not be represented as a warrant check.
How to interpret a Michigan search result
The record’s source identifies what it can prove. An MSP criminal-history response describes information in that repository; a court register describes a case; and an OTIS entry describes correctional status and history within MDOC’s scope.
Names alone can also create identification risk. MSP’s public tool is name based, while fingerprint-based procedures use biometric identification for authorized or personal-record purposes. Similar names and incomplete identifiers make cautious matching important.
Finally, an arrest segment, a charge segment, and a judicial disposition should not be collapsed into one label. Reading the sequence preserves the difference between suspicion, formal accusation, and the court’s outcome.
