A spokesman for the force said: “Officers were called to reports of a young male being attacked by four people with weapons at approximately 8.45pm on Back Beach, Teignmouth, and attended the scene where 50 to 100 people were present during the incident.

“The incident was part of a wider, large-scale disorder, which is thought to have involved teenagers and adults.”

Detective Sergeant Emma Boobyer, from Devon and Cornwall Police, said: “We have identified a teenage boy who has sustained minor head injuries.

“He has been checked over in hospital and discharged.”

‘Do not speculate’

Police also asked people not to share footage of the attack online.

Det Sgt Boobyer continued: “We are aware of footage circulating on social media and possible names being identified.

“We ask that people do not share this footage, and we need to remind the public that any suspect under the age of 18 is by law not allowed to be identified.

“These rules are not solely for media organisations to adhere to. They also apply to members of the public and includes information posted via social media.

“This may be seen as interfering with a live investigation we therefore remind the public that it is vital that they do not speculate on the identity of any suspects in this case.

“If you do have any information, please report it directly to us.”

The force said there will be a heightened police presence in the area during the weekend.
