X17 EXCLUSIVE - Police Investigate Possible Gun Use In Hollywood Hills Mansion Robbery Where Lindsay Lohan Was Present

Detectives from the Los Angeles Police Department spent three hours at the Hollywood Hills home where Lindsay Lohan spent the night Sunday evening, after a robbery was reported in the early hours of Monday morning.

A source tells X17online exclusively, "It looks like the owner of the home realized some of his personal belongings were missing this morning and he went crazy, accusing people in the house. He eventually called the cops to come investigate."

The home is owned by a man known to be a player on the Hollywood social scene but relatively unconnected to any celebrities in his business dealings. Our source tells us "he likes to have famous friends and he always opens his homes to parties as long as he can get A-listers to come and bring their friends."

It is uncertain who else may have been in the home at the time of the crime, other than Lindsay and her assistant Gavin Doyle.

Lohan kept her plans to fly to New York Monday night, despite the incident.
