One person has died and another is in hospital after a shooting on a nuclear submarine at Southampton Docks. One man has been arrested.

Police were called in by the MOD to investigate the shooting in Southampton Docks, today.

The incident happened on the nuclear submarine HMS Astute, which is berthed in Eastern Docks.

Four police cars, an unmarked police car and an ambulance were all seen going into the port at dock gate four.

The submarine is visiting the city as part of a drive to associate Royal Navy vessels with towns and cities across the UK.

The vessel arrived on Wednesday, following 46 days at sea for the 98-strong crew, for an informal five day visit.

The submarine was at 38/9 berth, with a 50 metre exclusion zone being patrolled by MoD police officers at all times.

Police say they are keen to reassure the public the incident is not terrorist related.
