British boxer Amir Khan reportedly landed a few blows on a gang trying to steal his Range Rover.

The 25-year-old and his younger boxing brother, Haroon, were believed to have been making their way to the car following a night out when they were met by six yobs blocking the pair's way.

"These guys tried to jump Amir and his brother but they picked on the wrong blokes," The Sun quotes an onlooker as saying. "They parked their car in front of the Range Rover. At least one had a cosh.

"One slapped Amir and clipped him on the lip but Amir pulled back and knocked him out cold. Then five of them went for Amir and Haroon but they stood their ground and these guys got dropped one by one. They left these men with cuts and bruises but all they were doing was defending their property."

The police later confirmed that nobody "came forward" following the incident.
