9:20 AM PT — Young Thug was released at 8:36 AM.
Young Thug is currently being booked at an LAPD station in Hollywood for transporting a firearm after cops found a cache of guns in vehicles belonging to him and his entourage.
Young was celebrating his birthday (as well as the release of his new album) at a Dave and Buster's in Hollywood and our law enforcement sources say that one of Thug's cars bumped a squad car belonging to the police department. During a subsequent search, several guns were found, including an AK-47. One of the cars was a Rolls Royce.
Our sources say several of the people on scene are currently being booked at the LAPD station, including Young Thug, whose real name is Jeffrey Williams. His bail has been set at $35,000 and he is still in custody.
Earlier in the day, Young Thug tweeted an invite to his "birthday celebration" at the bowling alley.
