BBC News is reporting that Ozzy Osbourne has been praised by police for "very courageously" tackling a burglar who stole jewelry from his house.
The singer grabbed an intruder who then jumped 30ft (10m) from a first floor window as the star gave chase at his Buckinghamshire home on Monday.
"I acted on impulse," Osbourne said. "In hindsight, it could have been a lot worse. It could've got really ugly."
A £100,000 reward has been offered for information leading to a conviction.
His wife Sharon, who called the police, said her wedding rings were taken from her bedside table as she slept.
The heavy metal star said he could have met the same fate as late Beatle George Harrison, who was repeatedly stabbed in a break-in in 1999.
"I could have been badly injured or shot or anything," Osbourne said. "I just thank God that no-one got injured."
He added he was glad the intruders were not hurt. "I wouldn't want anyone to get injured."
The singer did not want to talk in detail about his actions but when asked whether he would do the same again replied: "Is the Pope a Catholic?"
The incident happened at 4:00 a.m. GMT on Monday in Chalfont St Peter.
Detective Inspector Paul Miller of Thames Valley Police said it appeared a man used a ladder to get into the house through a first floor bedroom window.
"Whilst selecting items of jewelry, the burglar was disturbed by Ozzy who very courageously tackled this burglar and pursued him from the house," he said.
Ozzy said he was "just coming to grips" with what had happened and his opinion of the U.K. had been lowered after 12 relatively trouble-free years in the U.S.
"We lived in Los Angeles where people get shot every day and have been trailed by lots of different stalkers - and yet we come back to England and I'm very disappointed." Read more.
