LANSING, Mich. -

The Michigan State Police announced Friday the arrest of 51 non-compliant sex offenders during Operation Verify.

The operation, which ran during the month of Oct., was aimed at increasing compliance with Michigan’s offender registration laws. 

This was the state’s ninth annual sweep. 

More than 90 federal, state and local law enforcement agencies participated in the statewide operation where the homes of 1,742 registered offenders in Mich. were checked.

Police say the sweep saw 51 arrests and 116 warrant requests issued for violations of the Michigan Sex Offenders Registration Act.

As of October there were 40,155 people on the state sex offender registry.

A similar sweep in the city of Detroit recently led to 70 arrests for non-compliance.

What the Mich. Sex Offenders Registration Act says:

The act requires convicted sex offenders in Michigan to regularly report to their local law enforcement agency, sheriff’s office or nearest state police post to verify their address. 

A tier classification is assigned to each sex offender based on the requirements in the Act. 

  • Tier 1 offenders must verify their address annually, during the first 15 days of January. 
  • Tier 2 offenders must verify their address semi-annually, during the first 15 days of January and July. 
  • Tier 3 offenders must verify their address quarterly, during the first 15 days of January, April, July and October. 

Failure to comply carries a penalty of up to two years of incarceration. 

All registered sex offenders must also report a change of name, address, employment, campus enrollment, internet identifiers and vehicle within three business days of any change.
