2 Chainz Arrested For Weed, and Cops asked To Take Picture With Him... Lol

Says Cops Wanted Pics

2 Chainz was arrested for marijuana possession in Maryland last night ... and the rapper is PISSED -- claiming cops were just "f*ckin" with him ... and then asked him for pictures.

Who asked to take the photo... and a rep for the cops told us, "We cannot confirm who initiated that at this time."

Ummm ... how hard would it be to ask the cops???

2 Chainz was busted around 10 PM in Easton last night after Maryland State Police pulled over a white van he was traveling in ... along with 6 other people.

But cops say 2 Chainz was in possession of weed -- so he was arrested. He was the only person in the van taken into custody.

2 Chainz was taken to a nearby station where he was booked, released and even took a picture with police ... but the rapper says he only took the shot because THE COPS asked him for it.

After the incident, 2 Chainz went on a Twitter rampage -- saying, "dam police f*ckn wit a n**ga."

He continued, "Locked me up and then Wanted pictures smh (shakin' my head)."

2 Chainz also claimed that he didn't exactly have a bag of weed on him at the time ... only a grinder (a device used to crush up weed so you can smoke it.)

Interesting Point -- 2 Chainz posed the pic on his Twitter page... meaning it was most likely taken by someone in 2 Chainz's camp... which would mean the rapper probably initiated the shoot Oooooor... the cops took the pic and sent it to 2 Chainz.
