Drones have been temporarily banned from racecourses after jockeys complained about the noise they create.

The Racing Post has reported an incident at Newmarket last week which led to Frankie Dettori being unshipped and his horse running loose. Another jockey Ryan Moore and the race starter are also reported to have lodged a complaint.

Dettori is quoted as saying “the noise it made was like a swarm of bees but the thing to stress is this was an accident”.

The British Horse Racing Authority has suspended use of drones pending an inquiry.

Drones have been a recent addition to horse racing and were first used by Channel 4 last year during Royal Ascot.

The down side of their use has been the cost and also the fact they have been banned from flying over the closing stages of a race for health and safety reasons.

Drone shave been required to fly at a minimum height of 30m metres and 30 metres away from the track laterally.
