A spectator was arrested near Union Mills on Sunday afternoon after the Superbike TT race had been stopped.

A few minutes after the race had been red-flagged because of a last-lap incident at the Nook, race marshals at Ballahutchin called for assistance from the police following a disturbance.

Police dealt with four males who had been walking on closed roads and verbally abusing race marshals. One of the four was subsequently arrested for a public order offence and was detained at Police Headquarters.

The presence of the emergency services on the Snaefell Mountain Course forced the cancellation of the rescheduled RST Parade Lap, which was due to go ahead immediately after the race.

A police spokesman said that enquiries are continuing and issued a reminder that when roads are closed for racing, marshals have similar powers to police officers.

If members of the public do not follow their instructions they may face prosecution, they warned.
