People were stopped in their tracks by the eerie sound of a wartime siren going off in the city centre this morning.

A short video was taken of the wailing sound heard by Mathew Street, close to the Hard Days Night hotel, in a city centre still largely deserted because of lockdown restrictions.

One witness said: "I was sitting in the car and heard it.

"I thought I was hearing things - just weird."
