TELEVISION star Myleene Klass has reportedly warned by police for waving a knife at youths who entered her garden.

TELEVISION star Myleene Klass has reportedly warned by police for waving a knife at youths who entered her garden.

The presenter and model was in the kitchen of her Hertfordshire home with her daughter upstairs when she spotted the teenagers peering into her window just after midnight on Friday, according to reports.

She grabbed a knife and banged the windows before they ran away.

Hertfordshire Police officers warned Miss Klass she should not have used a knife to scare off the youths because carrying an "offensive weapon' - even in her own home - was illegal.

Her spokesman Jonathan Shalit said Miss Klass, who is originally from Gorleston, was "utterly terrified' and was stepping up security at the property near Potters Bar.

He told a national newspaper: "Myleene was aghast when she was told that the law did not allow her to defend herself at home.

"All she did was scream loudly and wave the knife to try and frighten them off.

"She is not looking to be a vigilante, and has the utmost respect for the law, but when the police explained to her that even if you're at home alone and you have an intruder, you are not allowed to protect yourself, she was bemused.'

Miss Klass' fiance Graham Quinn was away on business at the time of the scare.

A spokeswoman for Herts Police said no reference was made on the Klass incident report about a weapon.

She said: "We got a call at 12.45am (on Friday) to reports of the owner of the property hearing noises outside their address.

"They had been there for 45 minutes.

"Officers were in attendance and checked the property.

"There was no one around although they could see footprints in the snow.

"No property had been taken and there were no intruders.

"It was treated as a trespass incident.

"Words of advice were given in relation to ensuring suspicious behaviour is reported immediately.'
