Avon and Somerset Constabulary has issued a statement following the terror attack in London yesterday (Friday).

The UK’s terror threat level has been raised to critical meaning an attack is expected imminently following an explosion on a tube train at Parsons Green station yesterday morning.

Police have said it was caused by an ‘improvised explosive device’ and the person who placed it on the train has not yet been caught.

Twenty nine people have been treated in hospital following the incident.

Avon and Somerset Constabulary has issued the following statement which illustrates while there is no known threat to this area, the terror situation is constantly under review.

It says: “Communities across the UK can expect to see more officers, both armed and unarmed, on patrol by foot and in vehicles over the weekend. In particular, they will be patrolling at crowded places, iconic sites, transport hubs and ports.

“We’d like to stress that there’s currently no known threat to the South West and it is unlikely members of the public will see military on the streets of Avon and Somerset, although the situation is being kept under constant review.

“Our message is clear: please remain alert but don’t be alarmed. The increase in the number of officers on duty is designed to provide a highly visible and reassuring presence. We’ll do this for as long as necessary.”
