Advertisement >> John Anslow, 31, escaped following the attack on the prison van taking three inmates from Hewell prison in Redditch to Stafford Crown Court at about 8.20am. The van was stopped by three men wearing balaclavas who jumped out of a Volkswagen Scirocco. Two of the men were wielding sledgehammers and smashed the windscreen and the driver’s window of the GEO Amey prison escort van. The driver was also punched and reportedly threatened with a blade before the men drove off in the Scriocco. It is believed they switched to a silver Mercedes after stopping in Stoney Lane. The two other prisoners being carried in the van did not escape. West Mercia Police have now warned that Anslow, from Tipton, is considered "dangerous". He was one of five men charged with the murder of Richard Deakin, who was shot dead in Chasetown, Staffordshire, in 2010. The skip-hire boss was gunned down as he slept in his home in Meadway Street while his partner had taken their two daughters to school. CCTV images of the gunman calmly walking through their garden gate were screened on TV show, Crimewatch. Anslow was charged with murder alongside Mr Deakin’s brother-in-law Leigh Astbury. Hewell prison houses more than 1,400 inmates across three blocks holding category B, C and D prisoners. The incident is being investigated by officers from West Mercia Police. Anslow is described as white, 5ft 10ins tall, and of medium build with short brown hair.
