Detectives hunting for escaped prisoner Shaun Walmsley have offered a £20,000 reward for information leading to his recapture – taken from his own money.

Merseyside Police have used funds seized following Walmsley’s arrest and conviction for the murder of rival drug dealer Anthony Duffy, who was repeatedly and brutally stabbed in May 2014.

Detective Superintendent Natalie Perischine said: We have invested significant resources in trying to trace Walmsley to no avail, and we don’t think it is right that public money is being used in this way.

Walmsley, and those that released him, had put in a considerable amount of planning to execute his escape and it is only right that we use Walmsley’s own money to encourage people to tell us where he is.

Walmsley has been on the run since 21 February, when two men believed to have been armed with a gun and a knife confronted three prison officers who were transporting him between HMP Walton and Aintree University Hospital.

As the prison officers and Walmsley were getting into a car, the men threatened the officers and demanded they release him.

The 28-year-old and his accomplices escaped in a gold-coloured Volvo, which was later found abandoned in the Fazakerley area of Liverpool.

None of the prison guards were injured during the incident.

Six men and one woman have been arrested and released in connection with the escape.

Ten days ago detectives released a CCTV image that showed how much Walmsley had changed since the picture released when he was sentenced to life.

The image shows his face is more gaunt and he has lost a considerable amount of weight.

Walmsley, one of four men serving life sentences for the murder of Mr Duffy, is described as white, 6ft and of slim build with dark brown hair and blue eyes.

Detectives say the public should not approach Walmsley.

Both accomplices had their faces covered during the attack and were dressed in coats, trainers and tracksuit bottoms.
