The police who arrested Tom Sizemore in the early hours of Tuesday morning were investigating his assistant, not the troubled actor, RadarOnline.com can exclusively reveal.

The Saving Private Ryan star's personal assistant was arrested earlier in the evening for allegedly stealing a car and the investigating officers knocked on Tom's door in the early hours of Tuesday morning because his assistant is currently living there for free, Sizemore's rep told RadarOnline.com in an exclusive interview.

"Tom was at his own house in Los Angeles - not someone else's apartment - the confusion came about because the assistant is living at his house but not paying rent," explained his spokesperson. "No drugs were found there and he wasn't doing anything wrong."
