Lil Baby spent Monday night in jail after being arrested in Las Vegas for possessing an illegal weapon.

The Las Vegas Metropolitan Police arrested the 29-year-old (Dominique Armani Jones) for carrying a concealed weapon without a permit – a felony – and he’s being held on $5K bail at the Clark County Detention Center, according to TMZ.

Lil Baby was last seen on Sunday night while attending Los Angeles Clippers point guard James Harden’s 35th birthday party at MainRó in Hollywood. The Las Vegas Metropolitan Police have yet to release details about the alleged crime.
