A sleepwalking Irish teenager escaped with only minor injuries after falling from a second floor apartment, while on vacation in Majorca, Spain.

Rob Casserly (19) originally from Bray, County Wicklow was holidaying with 15 friends when he went sleepwalking during his first night of his vacation according to the Star newspaper.

Miraculously he emerged with a broken ankle and a cut lip after he was brought to hospital to recover from his injuries.

The teenager had ventured out for a few drinks with his friends but retired early to bed before wandering out of his apartment and climbing over a railing.

The incident occurred shortly after 8am last Sunday morning at the Verdemar Apartments in Santa Ponsa.  A waitress saw the student hanging from the railings but was unable to get to him before he fell.

His father Derek Casserly told The Star he has no memory of the incident.

“He is fine. He is very lucky,” he said.

“He remembers going to bed and then waking up in hospital. But he has been prone to sleepwalking in the past.

“We are all very relieved. He should be getting discharged (from hospital) later this afternoon.”

A spokesman for Son Dureta Hospital in the Majorcan capital Palma told the Irish Independant: "We have operated on a 19-year-old Irish boy who suffered a broken ankle."
