Police Try To ID Man Found Seriously Injured
A man is in hospital with serious head injuries following an alleged assault.
Police were called to New Row in Dunfermline, Fife, at around 1.50am on Sunday.
A man, thought to be around 30, was found to have sustained serious head injuries and was taken to Victoria Hospital in Kirkcaldy.
A man has been detained in connection with the incident.
Officers are currently working to identify the injured man and are appealing for anyone who recognises his description to come forward.
He is described as being around 6ft, with a slim build and short brown hair.
He was wearing dark blue denim Voi jeans with a New York design belt and a white T-shirt. On his right arm is a black tribal-design tattoo that starts at the top outer of his arm and reaches down to just above his elbow.
Detective Inspector Chris Mill said: "At this time a man is detained in connection with this incident, however we'd urge any further witnesses to get in touch.''
Anyone with information can contact Police Scotland on 101 or Crimestoppers on 0800 555 111.
A police watchdog probe was launched after the remains of the 52-year-old were found in a house in Dumfries in February last year.
The accident happened at about 7.50pm on Thursday in Moodiesburn, North Lanarkshire.
More than 70 firefighters were needed to bring the blaze under control at Blochairn Fruit Market in the early hours of Thursday.
