A TEENAGER was detained by members of the public after reportedly spraying people with an ‘unknown liquid’ at a retailer in Avonmouth.

Emergency services were called to Costco in Avonmouth, Bristol, just after 6.30pm on Monday, February 17.

Police, fire and ambulance crews attended in a co-ordinated multi-agency response.

Ten people – including the boy – were complaining of stinging or itchy eyes and skin. Store staff provided first aid until ambulance crews arrived.

Avon and Somerset Police said in a statement: “People responded well to treatment and were discharged by the ambulance service at the scene.

“The liquid is believed to be a type of home-made “chilli spray” with no strong acid or alkaline ingredients.

“A juvenile was arrested on suspicion of attempting to cause grievous bodily harm and administering a noxious substance, and remains in police custody.

The incident concluded by about 8.30pm and police resources cleared the scene by 9pm.”

Anybody who saw what happened or may have footage or information which could help the investigation are asked to call 101 with reference number 5225042707.
