Wiz Khalifa has been arrested in Texas on suspicion of having marijuana.

Police say the rapper was searched because he didn't have identification when he was stopped at a checkpoint at El Paso airport.

The "Black and Yellow" singer has been charged with possession and was released on police bail.

The star hasn't commented but did tweet a selfie and some more photos from his jail cell with one entitled 'Free Trap Whiz'.
