Fall Out Boy singer Patrick Stump has been arrested on a traffic warrant for driving without a licence.

The rocker was arrested in Hollywood in the early hours of Wednesday morning.

A warrant had been issued for his arrest for the driving offence by a Beverly Hills court.

Stump was released on $15,000 bail at about 4.30am.

It is not the first time Stump has been in trouble with the law.

Cops threatened to arrest him and Fall Out Boy bassist Pete Wentz last December for trying to play an impromptu gig in a New York park without a licence.
