Intruder Detained at Paris Hilton's Home

Cops have just detained a man at Paris Hilton's L.A. area home -- after the guy allegedly snuck past a guard gate and knocked on her front door ... TMZ has learned.

Law enforcement sources tell us private security immediately sprung into action -- and tried to apprehend the man, who was riding a bike. We're told the man tried to put up a fight, but to no avail.

The security officers were able to physically restrain the man until LAPD officers arrived on scene and took him into custody.  The suspect was transported to a nearby police station for questioning.

Hilton had to deal with another scary situation at her home back in August -- when a man carrying knives allegedly tried to break into her home. Her BF pulled a gun on the suspect before anything happened.

No word if the two incidents are connected.

UPDATE:  We've learned the suspect is James Rainford.  He's being held on $20,000 bail.  He's been booked on battery charges.
