Prison guards held 'at knife point' as Shaun Walmsley escapes

Police have released CCTV of the shocking moment two hooded thugs 'armed with a gun and a knife' forced officers to hand over a convicted murderer who was being escorted on a hospital visit.
Shaun Walmsley, 28, escaped from Aintree University Hospital in Liverpool on February 21.
Two men believed to be armed with a knife and a gun confronted prison officers guarding the HMP Walton inmate at the hospital.
A gold-coloured Volvo, which was used for the escape, was later found abandoned in the Fazakerley area of the city.
Walmsley was serving life with a minimum term of 30 years for the murder of Anthony Duffy, 33, in May 2014.
None of the prison guards were injured during the incident.
Detectives hunting the escaped prisoner have put up £20,000 of the inmate's own money for information leading to his capture.
The reward is made up of cash which was seized by Merseyside Police after Walmsley was arrested and convicted for a murder he committed in 2014.
Detective Superintendent Natalie Perischine, said: 'We have had a really good response from members of the public around the country following our appeals, but we still need that crucial information about his present whereabouts.
