Emergency services descended on Newcastle's Utilita Arena as they practiced their response to a terrorist attack.
Tyne and Wear Fire and Rescue Service (TWFRS) led a training exercise on Thursday, October 20 that saw them work alongside Northumbria Police and the North East Ambulance Service (NEAS) to deal with a simulated incident at the arena.
Volunteers played the parts of casualties, allowing agencies involved to test how they would locate suspects, treat injured people and protect the public.
