A Los Angeles Police Department SWAT team surrounded the actor's home in the 2500 block of Hargrave Drive at around 1 p.m. Wednesday as an unidentified woman, armed with a knife barricaded herself inside. The standoff lasted for nearly five hours.
Thomas starred as "Finch" in the "American Pie" movie series. He was not in the home at the time of the standoff.
Police fired tear gas and flash grenades into the house, and then entered and arrested the woman.
It remains unclear why she barricaded herself inside. Investigators have yet to release the name of the woman.
