On my way to the Sunshine Garden Centre, (usually a fairly tranquil stroll) I noticed that at the bottom of Wroxham Gardens the street running off of that at the back of the Sunshine Garden Centre was blocked off. Residents had been told to leave their homes.

There was a fire engine and a strong police presence with  about six police vans as well as police cars.  A helicopter was circling overhead. 

Apparently a 'suspicious substance' had been found in a shed.
