A man accused of breaking into the home of Paris Hilton armed with knives pleaded not guilty to a charge of attempted burglary.

Nathan Parada, who entered the plea in a Los Angeles court on Friday, was arrested on August 24 outside the socialite's house, reports the Mirror.

Hilton was at home when Parada allegedly banged on windows.

She posted a photo of his arrest on her Twitter feed and described the incident as "scary".

Parada is due back in court for a preliminary hearing on September 15. (ANI)
