2 Chainz was in Maryland last night where he was arrested for marijuana possession.

Chainz, who argues that police were just messing with him, was taken into custody at around 10 PM last night. Maryland State Police pulled over a white van that contained Chainz and six members of his entourage.

Apparently, when Chainz was taken to a station and released, the police wanted to take pictures with him. It is still unclear who asked to take the photo—Chainz or the cops—but he went on a Twitter rant shortly after.

2 Chainz claims he wasn’t in possession of marijuana at the time. It was actually a grinder, which is a device used to crush up weed to roll up in papers or cigars.
