Michigan State Police drug investigators raided 2 medical marijuana dispensaries in Ann Arbor today, but said the raids had nothing to do with a state appeals court ruling Wednesday that prohibits dispensaries from selling marijuana. Michigan State Police drug investigators raided 2 medical marijuana dispensaries in Ann Arbor today, but said the raids had nothing to do with a state appeals court ruling Wednesday that prohibits dispensaries from selling marijuana.

Witnesses said 3 people were taken into custody.

Det. 1st Lt. Wynonia Sturdivant of the Livingston and Washtenaw Narcotics Enforcement Team said MedMar clinic at 1818 Packard St. and A2 Go Green Corp at 206 S. Main St. were raided because their employees allegedly failed to follow guidelines established for operating dispensaries. She declined to be more specific.

Sturdivant said both dispensaries have been under investigation for at least a couple of weeks and the raids are not related to each other. She said she did not know what was seized.

"It's an ongoing investigation," she said.

Police officers dressed in black and wearing masks executed a search warrant at MedMar about noon, seizing computers, boxes, plastic bags and other items. Witnesses said 3 people were taken into custody as part of that investigation.

Shortly after noon today, officers executed a search warrant at A2 Go Green Co-op, seizing boxes of files, computers and brown paper bags. U.S. Postal Inspection Service agents were there, but Sturdivant declined to say why the federal agency was involved.

Police vehicles were parked in the middle lane of Main Street for at least 45 minutes.

Chuck Ream, longtime medical marijuana advocate and partner at MedMar, said two of his employees, were taken away in handcuffs about 10:30 a.m. Another employee was arrested later in the morning.

Ream and 3 other people were holding signs promoting medical marijuana and protesting the police action, yelling at the officers who were carrying items out.
