Man Seriously Assaulted in Glasgow Attack
A 42-year-old man's in a serious condition in hospital after he was attacked in Glasgow city centre.
It happened at about 02:55 on Saturday on North Street close to Sauchiehall Street at Charing Cross.
The man was taken to the Glasgow Royal Infirmary and then transferred to the Queen Elizabeth University Hospital where medical staff describe his condition as serious.
Detective Sergeant Kevin Browne, Drumchapel CID, said: "From our early enquiries, this was an unprovoked attack on a man making his way home from a night out.
"The 42 year-old man was punched by another man who then made off in the direction of Sauchiehall Street.
"Our enquiries have been continuing through the night. Officers remain at the scene.
"We have been analysing CCTV and speaking to people who were in the area following the incident. At this time, we are seeking information from anyone who has information which can help trace the man responsible.
"You may have witnessed the disturbance, you may have witnessed a man running down Sauchiehall Street towards the City Centre. Please contact police with any information you may have."
Westminster's Scottish Affairs Committee said the proposals showed "a lack of planning''.
Holyrood's Sport Committee has warned the Protection of Vulnerable Groups (PVG) system "may not be preventing unsuitable people from doing regulated work''.
