LONDON: British police said Friday they had arrested four men on suspicion of brandishing a gun at tennis star Andy Murray, although media reports suggest they were fans with nothing more threatening than a tennis racquet.

The suspects’ car was stopped and searched and “no trace of a firearm was found,” Scotland Yard said in a statement, adding that the men had been released on bail pending further investigation.

According to the Sun newspaper, the men tapped on the window of Murray’s stationary car after a book-signing in London on Wednesday, trying to get him to sign a racquet.

The Wimbledon champion drove off so they got back in their Mercedes — but not before a member of the public had called the police and reported that one of them had a weapon.

“Police were called on Wednesday by a member of the public reporting that they had seen a male in a Mercedes car in Avenue Road in possession of a firearm,” the police statement said.
