Members of staff at a petrol station in Bristol have been rescued by police unharmed following a two-hour siege.

Staff of the Morrisons Daily Store at the Esso petrol station on Hengrove Way retreated to a safe room after a man carrying a knife came into the store at around 7.30am on Thursday 9 September.

A 999 call was received by Avon and Somerset Police at 7.36am and officers attended by 7.41am. The road was closed as a precaution and after two hours of negotiations officers detained a man.

People in the area heard a number of bangs which came from police distraction devices being deployed and a baton round that was discharged.

A police statement said these were “minimal force options and presented the least risk to the public, the suspect and officers in bringing the situation to a safe conclusion.”

Members of staff on site were uninjured having remained in a safe room and in contact with officers.

A man in his 50s was at a police custody unit having been arrested on suspicion of attempted murder and will be assessed by health professionals.

One person had left the scene and made their way to hospital with knife wounds. He was a man in his 20s and was treated for injuries that were not believed to be life-threatening.

Investigations continue and neighbourhood officers patrolled the area to reassure the community.

Police urged anyone who saw the incident or had any other information which could help to call 101 quoting reference 5221208981.
