An attempt by four men to rob security personnel at the Somerset branch of HSBC ended with no injuries yesterday.

One of the suspects brandished what appeared to be a firearm during the 2pm confrontation, before the four feld on foot. Bank personnel remained at the scene afterwards as a police forensics team went over a security van.

Area MP Michael Scott expressed relief that no one had been hurt, encouraging the public to help in the police investigation in any way possible.

Inspector Paul Simons said the first man, believed to have been holding the firearm, was about 5ft 3in and wearing a blue and red ski mask with a maroon helmet. The second man was 5ft 3in and dressed in dark clothing, while a third man was 5ft 9in and was wearing a white helmet with beige pants.

The fourth man was 5ft 11in and dressed in dark clothing and was also wearing a black helmet.

Anyone with any information is urged to call the police on 295-0011 or the confidential Crime Stoppers hotline on 800-8477.
