*A member of the group Mindless Behavior is being sought for questioning by LAPD over his new BMW…which may or may not be stolen.

According to TMZ, record producer Chris Clark’s BMW 325i went missing Monday following a Hollywood studio session with band member Roc Royal. Clark reportedly left the car keys on a table in the studio, and when he went to leave, the keys — and Roc — were gone.

Meanwhile, Roc Royal was seen tooling around L.A. in a brand new Beemer, according to TMZ.

We’re told Clark contacted Roc Royal and threatened to call the police if the car wasn’t returned immediately … but Royal refused so Clark reported the vehicle stolen.
