A man had to be treated for an eye injury after five people were sprayed with an ammonia-based liquid at a Burger King in Clacton last week.

It happened around 3.30pm on September 14 at the fast-food store in Stephenson Road.

Two men walked into the restaurant and sprayed the fluid at four other men who were waiting for food. All six then ran from the restaurant.

Another man, who was not connected to the suspects or victims, was caught up in the melee and had fluid sprayed in his face. He later required treatment for an eye injury.

About two hours later police were called to Hayes Road, Clacton following reports of a fight involving men armed with baseball bats and hockey sticks. Detectives believe the incidents are linked.

Investigating officer detective constable Rob Dines said: “There were a few other customers in Burger King at the time and we would like to hear from anyone who was caught up in the altercation and was accidentally sprayed or affected by the substance.

“Following the incident, two men ran from the restaurant and towards the car park entrance. One of them was black and was wearing a black T-shirt and the other was white and wearing a red baseball cap.

“The area around the shopping village was busy and we would also like to hear from anyone who saw the men or saw a vehicle leave the area at speed.

“After the incident at Hayes Road a man contacted police and gave some information but did not give his details. We would like him or any other witnesses to contact us.”

Anyone who can help should contact DC Dines or his colleagues at Clacton CID on 101 or call Crimestoppers anonymously on 0800 555111.
