WARREN, Mich. (AP) — A lawsuit against the city of Warren seeks up to $5 million in damages on behalf of 23 state-approved medical-marijuana users who say they’ve been harassed by police.

The Detroit Free Press reports the lawsuit, filed Monday in Macomb County Circuit Court by attorney Michael Greiner, also says Warren zoning officials, police and Mayor Jim Fouts cooperated to shut down a medical marijuana center that was raided Sept. 18.

The Macomb Daily of Mount Clemens reports the suit also says police on Sept. 17-18 illegally stopped drivers leaving the Michigan Safe Transfer Center.

Fouts tells WJBK-TV that he denies ordering any sort of a police presence at the center and says he was surprised by the lawsuit.

Michigan voters approved marijuana use for some chronic medical conditions in 2008.
