Lil Pump is sporting some new jewelry -- an ankle bracelet after he was put on home arrest when cops busted him for firing a gun inside of his house.
Law enforcement sources tell us the 17-year-old "Gucci Gang" rapper was busted Wednesday at his house in the San Fernando Valley. The official charge is shooting at an inhabited dwelling.
We're told Pump shot a hole through his front door. Cops were unsure of the nature of the shooting at first and even dispatched a chopper into the air to search for suspects.
Sources tell us when he arrived at the LAPD station, he appeared "very chill."
Law enforcement sources tell us Pump was then booked into the Los Angeles Central Juvenile Hall and released shortly after. We're told he has been ordered under house arrest, and is now wearing an ankle bracelet.
