This is the moment a Thai serial killer was caught on a train this morning (December 18) after allegedly being released from prison and murdering a sixth victim.<br /><br />Somkid Pumpuang, 55, was sentenced to life in 2005 for the killing of five women in the country's nightlife industry - drawing comparisons to the infamous Victorian killer who prowled London's East End. <br /><br />He was deemed an "excellent prisoner" and released in May, the Thai corrections department said in a statement today. <br /><br />Police began hunting Somkid again after hotel maid Rasmee Mulichan, 51, was found murdered in Khon Kaen, north-eastern Thailand, on Sunday (December 15).<br /><br />Footage shows how he was captured riding on a train in Korat province on December 18. <br /><br />The convicted murderer is believed to have targeted his latest alleged victim on Facebook by posing as a lawyer.<br /><br />He is said to have befriended her online before moving in with her and telling her that he wanted to marry her and even planning a ceremony.<br /><br />But Rasmee was found dead from suffocation with an electric wire fastened around her neck and her wrists and ankles tied, authorities say. <br /><br />Rasmee's devastated cousin Laddaporn Arjsak, 28, said her relative had told her that the pair were planning to get married on Sunday.<br /><br />Laddaporn said: ''My cousin loved him and she told me that they were getting married on Sunday. Instead she is dead. I want the police to find him so we know what happened. If he has killed someone again he should never be allowed out of prison.''<br /><br />Neighbours allegedly told police that they heard Rasmee calling for help on Sunday morning but when they knocked on the door, Somkid answered and said there was no problem. <br /><br />He is then believed to have fled through a window at the back of the property before the body was found later when neighbours checked again.<br /><br />Somkid's fingerprints, clothes and paperwork relating to his car were allegedly found at the scene. <br /><br />Police chief Chatchawin Srikaeolor said several stations in the area are cooperated in the hunt for the serial killer. <br /><br />He said: ''We believe that the murder took place on Sunday morning.''<br /><br />Authorities offered a 50,000 baht (£1,250 or $1,650) reward for information leading to Somkid'scapture. <br /><br />Thailand's corrections department said it was urgently reviewing the sentence reduction policies but also said it was operating at three times capacity with 370,000 inmates.
