Police in the US have launched an inquiry into why Sean "P Diddy" Combs was given a police escort after a concert.
The New York City police department says the assistance by a sergeant for one city block was unauthorised and is under investigation.
Police say the Friday night escort was requested by the hip-hop star's dry cleaner, who asked several officers before the sergeant agreed.
One police van escorted Diddy from the Hammerstein Ballroom to just near the entrance for the Lincoln Tunnel. The department says claims that several officers escorted the music star to New Jersey are false.
Mayor Michael Bloomberg says security is the only reason anyone should get a police escort.
A representative for Diddy made no comment.
Police officials in Washington DC recently attracted attention when they gave actor Charlie Sheen an escort before a performance.
