Two dangerous inmates, including a convicted murderer, are on the run after escaping from a prison on New Year's Day, according to police reports. Matthew Armstrong, 35, who was convicted of murder during a robbery in Warwickshire in 2009, and Daniel Washbourne, 40, with previous convictions for violence and false imprisonment, are believed to have left HMP Leyhill, South Gloucestershire, between 5 pm and 8 pm on Thursday. The police have issued a public appeal for information, warning that the pair are not from the local area and have connections across the country. CCTV footage shows the men on New Year's Day, and the police have taken immediate action by circulating their images as wanted individuals through national police systems. The investigation is ongoing, with intelligence efforts tracing their movements and address checks proving negative so far. The public is urged not to approach the suspects but to call 999 with the reference number 5226000700 if they recognize either individual.
