Snooki goes to Jail....Take 2!!!

"Snooki was taken into custody in Florence, Italy Monday after crashing into a police car. Snooki was driving when she struck the cop car, but sources connected with the production tell TMZ, "Zero alcohol was involved."

We're told no one was injured.

A witness tell TMZ, Snooki smacked her into the back of the patrol car, wedging her ride between the car and a highway protection wall. The witness says JWoww was with her at the time of the crash -- and when she tried to exit the car, she had to go through the window ... because the door was blocked by the wall.

A source connected to the production tells TMZ, although Snooki is in custody ... it is not a formal arrest."
