Police arrested singer George Michael for possessing drugs after finding him slumped over the steering wheel of his car in London, authorities said Monday.

Police arrested Michael early Sunday after responding to complaints that a car was blocking an intersection in north London. He received a caution for possession of cannabis and was released on bail on a charge of being unfit to drive. He has a November court date.

Just a week earlier, Michael gave his first solo concert in 15 years. The concert in Spain kicked off his new tour, "25 Live," which is booked at 28 European cities this fall.

Michael first rose to fame in the 1980s as half of the duo Wham! before starting his solo career.

Police had earlier warned Michael for possession of cannabis in February.

In April, he hit three parked cars. He later acknowledged in an interview that he was a "terrible driver" and said he was trying to maneuver out of a parking spot.
