The family of an Ayrshire man brutally assaulted and left in a coma while on holiday in Ibiza say his injuries are more serious than they first thought.

Gavin Roberton, 26, has been fighting for his life in a Spanish hospital after he was randomly punched in the head while at an ATM.

His devastated mum and aunt flew to the island to be at the stricken Stewarton electrician's bedside after he suffered a fractured skull, as well as bleeding and bruising on his brain.

Now, his family believe his injuries are even more serious than they first thought, and say he could remain in a coma for some time.

Aunt Paula Marshall said: "We are now into nightmare week two.

"Gavin is still stable but will be kept in the induced coma for longer than expected.

"Scans showed that there is still an issue with swelling and the damage is a bit deeper than first thought.

"The doctors are confident he just needs more time to heal."

Paula and Gavin's mum, Kirsty, have been at his bedside every day - and say they are becoming part of the furniture in the Intensive Care Unit.

A fundraising drive to support Gavin and his family has reached almost £40,000 in just 12 days.

Speaking to the Irvine Times, Gavin’s uncle said the family are just taking one day at a time but are “overwhelmed” but the support from the public.

He said: “Everyone is coping but obviously it is very difficult because he is in another country so we aren’t able to see him.

“His mum Kirsty and my wife Paula are with him and keeping us updated and they are keeping each other going.

“I don’t think anyone expected the response from the public. We have been overwhelmed with the amount that’s been raised, but it’s about more than the money.

"It’s about people showing their support for Gavin which has been amazing.”
