Manchester United players have been caught up in a bomb scare in Los Angeles.

A bomb scare has forced an evacuation at the UCLA campus where Manchester United and Real Madrid have based themselves for pre-season training.

The incident took place at around 10pm local time in Los Angeles, which was 6am in the UK, but neither side were present at the time.

The LA Times reports at least three residence halls at the Westwood campus were evacuated, with students being ushered to the campuses Drake Stadium.

University of California police Capt. Bob Leinweber confirmed that a recreation centre had been searched with four bomb-detecting dogs, but no explosives had been discovered.

“We've just about concluded the search and nothing found," Leinweber said.

A UCLA spokesman confirmed that the evacuation was merely "precautionary".
