An 81-year-old granddad has been put under house arrest by his family after a bizarre accident turned him into a sex addict. Frail Angelo De Luca was in a coma for four days after he fell out of a plum tree at the family home in Biasca, Switzerland.

But coming round from an operation his family were horrified to watch their devoted widower dad turn into a randy teenager again.

Sex mad Angelo blew £3,000 of his savings in one session at a local brothel after falling head over heels for a hooker young enough to be his granddaughter.

"Since my wife died a year ago, Leona has been there for me. It's not only that she's good in bed. She gives me new life force and courage. She is my friend, my only confidant," he said.

But his son Daniele has taken control of his dad's two houses and bank accounts after judges ruled that his sex addiction made him unfit to govern his own affairs.

"That woman preyed upon my father like he was a Christmas goose," he said.

Now the family are suing the hospital for medical negligence.

"My father broke seven ribs and his lungs were pierced in the fall. He had to wait for three weeks for surgery.

"He had severe pain and the nurse gave him morphine, maybe too much. My father fell into a coma for four days. That must have wiped out a brain function. The one that inhibits the sex drive," he added.

But hospital chiefs deny any medical blunder. Director Michele Morisoli said: "Our staff acted to the best of their knowledge and conscience."
