Three teenagers have been arrested after a 17-year-old was injured in a suspected sword attack near a school in Gloucester.

Officers were called to Chalford Road, near St Peter’s high school, in Tuffley, shortly after 8.50am on Friday. It was reported that two people, one in possession of a sword, had been seen chasing two 17-year-olds. The suspects then fled the scene on foot.

One of the victims sustained a “superficial wound believed to have been caused by the sword”, Gloucestershire constabulary said. The other young person was not physically injured.

Armed police attended the scene to search for the suspects. St Peter’s high school and the nearby Willow primary academy were put on lockdown on Friday after the attack.

A 19-year-old was arrested overnight, while an 18-year-old handed himself in to the police on Saturday morning. A 17-year-old boy was then arrested later on Saturday.…
