London Metropolitan Police raided a KFC on Tuesday evening after a teenager waved a gun at the fast food restaurant. 

"At around 6.30pm, we received a call from a member of the public who had seen a group of youths in possession of knives and a firearm in the Grove Retail Park in Goodmayes," a Met Police spokesperson told the press in a statement. "Officers responded quickly, including armed response units."

Police stormed the restaurant to arrest the youths, some of whom had knives. The gun remained the primary focus of the police response.

Social media footage captured the moment when dozens of officers with guns and body armor rushed in while the group sat at a table, The Evening Standard reported.
