Singer George Michael has been cautioned for possessing cannabis after being arrested in north London.
George Michael was found in his car in north-west London
The 43-year-old star was arrested on Sunday after motorists called police to report a car causing an obstruction at traffic lights in Cricklewood.
Police confirmed the driver was arrested on suspicion of being unfit to drive and drug possession.
He was later cautioned and released on police bail pending further inquiries on his fitness to drive.
Police said an ambulance was called and Mr Michael was taken to a west London hospital as a "precautionary measure" after he was arrested.
A Scotland Yard spokesman said: "At approximately 3.22am on Sunday morning officers were informed of a stationary vehicle with a driver inside causing an obstruction at traffic lights in Cricklewood Lane near its junction with Hendon Way, NW2.
"Officers arrested a 43-year-old man on suspicion of being unfit to drive and possession of a controlled substance believed to be cannabis."
A spokesman for Mr Michael did not comment on the arrest or caution.
In February Mr Michael was cautioned by police for possessing cannabis after being found in his car at Hyde Park Corner, central London.
The singer recently embarked on his first live tour for more than 15 years, with the UK leg due to begin in November.
