A TEENAGE worker is in a serious condition in hospital after suffering "horrendous injuries" in a 40ft fall from a penthouse terrace at one of Glasgow's most luxurious hotels.

The 19-year-old, who worked at the five-star Blythswood Square, had been at a party thrown by a former employee when he fell and landed on spiked metal railings in West George Street at around 5am on Wednesday.

The friend had booked the £1,500-a-night suite, where celebrities such as Beyonce and P.Diddy have reportedly previously stayed.

Emergency services were called after the man was found on the pavement.

A foot-long spike from metal railings was found nearby.

He is being treated at ­Glasgow Royal Infirmary.

Inspector Kenny Darroch said: "He's alive, but he has horrendous injuries."

Hans Rissmann, ­managing director at Blythswood Square, said the thoughts of all the young man's colleagues were with him and his family.

He said: "Contact has been made with his relatives. Everyone's thoughts are with them.

"The hotel is providing every co-operation to the authorities.

"A full inquiry will be undertaken in order to understand the circumstances surrounding this accident."

A student whose room overlooked the scene said: "I woke up and the place was swarming with police.

"I asked the hotel what was happening and they said there had been an ­accident. I assumed it was a car accident.

"I was so shocked when I found out what actually happened. It's horrible."
