Rich Homie Quan was arrested and detained by police over Memorial Day weekend.

While en route to his show at Club Liquids in Wadley, Ga. on Saturday night (May 28), the Atlanta rapper and his crew were stopped at a police checkpoint, reports TMZ. Quan and five other men were arrested on suspicion of possession of a stolen gun and drugs, which law enforcement officials believe to be ecstasy and weed.

As of Sunday afternoon, the “Flex” hitmaker was in Jefferson County Jail, but has yet to be charged. An investigation is ongoing and it’s currently unclear if he will be charged.

Meanwhile, Quan continues to work on his oft-delayed debut album Rich as in Spirit, which is set to feature Lil Wayne, Ashanti, Jadakiss, and Boosie Badazz.
