Exclusive 1117_colin-farrell_tmzColin Farrell got an unexpected, and unwanted, visitor at his home in Los Angeles this weekend — and now the guy”s been arrested and placed on a psychiatric hold. 

Law enforcement sources tell our sources … a man showed up to Colin”s home Saturday afternoon hoping to catch a glimpse of the actor … but things got weird when he walked right up to the front door.

We”re told Colin was home at the time and got freaked out … so he called his assistant who called cops.

The fan was quickly taken into custody and after cops spoke with him — they decided to put the suspect on a 5150 psychiatric hold.

Police haven”t released the suspect”s name — but our sources say he is not a U.S. citizen, and one of the reasons he came to L.A. was specifically to see Colin.
