A convicted murderer is on the run after armed men helped him escape during a hospital visit in Liverpool.

Shaun Walmsley, 28, is one of four men serving life sentences for a fatal stabbing in the Aintree area of Merseyside in 2014.

He fled from outside Aintree University Hospital as he was getting into a car with prison officers.

Merseyside Police said two men, believed to be armed with a gun and a knife, assisted in the escape.

Officers said the men threatened the guards and demanded they release Walmsley, before making off in a gold-coloured Volvo.
