My message to the public is one of reassurance – incidents involving a firearm are very rare in this area, and we will not rest until we have established what exactly has happened. > We believe this to be an isolated incident and all parties are known to each other. We are not currently looking for any other individuals in connection with this investigation.
A police cordon remains in place and Blue House Lane is closed between Albany Way and the roundabout at Havannah Road.
Drivers are being urged to use a different route.
