A SCOTTISH student has vanished after a night out with pals in Spain - leaving his dad "extremely worried" as loved ones and police frantically try to find him. Fears are growing for Edinburgh University history student Gregor Thomson after he vanished in Madrid in the early hours of yesterday morning. The 6ft 2in rugby player only arrived in the Spanish capital on Friday morning with teammates for a weekend trip but lost contact with them after they left Diverzo Cocktail Bar when Gregor ran back in to retrieve something he had left. Gregor's dad Murray, from Edinburgh, said no one has seen or heard from him since. He said: “No-one’s heard from Gregor since the early hours of Saturday morning and we’re obviously all extremely worried. “He had only arrived in Madrid around 9.30am on Friday with rugby teammates for a weekend away. “We’ve been told he became separated from them in a bar called Diverzo Cocktail Bar. “They’d obviously had a few drinks so things are a little bit hazy but the people he was with say he wasn’t talking to anyone else or doing anything out of the ordinary that might explain a disappearance like this. “My son is a sensible lad and he’s never gone missing like this before. “The police are involved and are doing everything they can including trying to get hold of CCTV in the area where he was last seen for clues. “Gregor was staying in a hostel with the other lads who are also helping out as much as they can. “His phone is dead and we don’t know if he still has it with him. He had his wallet on him. “They are all due to fly back home tomorrow (MON) around lunchtime. “I urge anyone with any information about my son to please contact the authorities as soon as possible. “We’re just praying for good news.” Gregor’s cousin Amy Hood added in a social media post: “Gregor was on holiday with his rugby friends and was separated from the group. He is 21 years old, 6ft 2/3 with dark hair.” Friend Liv Anderson took to Facebook to appeal for help. She said: "He is part of a rugby team from Scotland and was with his teammates at the bar. “They all left together. However he returned to the bar on his own to retrieve something he had left. He has not been seen since then. “His teammates and captain had been at the police station yesterday and the police officially named him as a missing person last night. “His phone is dead (most likely) and we don’t know if he has ID on him or knows exactly where he is, as it was their first day and he does not know Madrid. “If anyone has seen him or has any information please reach out immediately. Please share this if you can, to help spread the word. Call 112 for police.” Spanish police could not be reached today for comment.The missing Brit is understood to play for Edinburgh-based Stewart’s Melville RFC.
