Osbournes ramp up on security

Rocker Ozzy Osbourne has ordered extreme new security measures at his mansion to prevent a repeat of the £2m (€2.8m) jewellery theft earlier this week.

The former Black Sabbath star bravely held one of the two intruder's in a headlock and dangled him out of a window at his Chalfont St Peter, Buckinghamshire home before the thief struggled free, escaping with irreplaceable gems, including his wife Sharon's wedding and engagement rings.

But the 55-year-old is making sure he's prepared for future trespassers, by hiring 24-hour security guards and installing laser "tripwires", guard dogs and a series of watchtowers.

An insider explains: "He's shocked and angry. He can't understand how what he thought was a good security system failed."
