Drug Enforcement Administration Special Agent Rich Isaacson confirmed to AnnArbor.com that federal agents executed a search warrant Tuesday at the dispensary, located at 2245 W. Liberty St. near Stadium Boulevard.

City officials said they have no official estimate on the number of dispensaries, but one owner, Daryl Mynes, the 31-year-old co-owner of People's Choice Alternative Medicine, which opened in July and has 1,300 club members, said Ann Arbor could already have as many as 30 since the state law took effect.
