Police are reportedly in a standoff with Sandra Bullock's stalker Joshua Corbett, who was arrested in 2014 for breaking into Bullock's house, according to TMZ. 

The site says police went to Corbett's Los Angeles home Wednesday morning (May 2) to arrest him for violating the terms of his probation (it's still not clear what the violation was) but "he threatened harm on them and barricaded himself in his home." Now, a S.W.A.T. team has been called to the scene and nearby streets have been closed down.

TMZ adds that Bullock was fearful when Corbett was released from a mental health facility last year. She currently holds a restraining order against him that's good through 2022 that is meant to keep him at least 200 yards away.

According to New York Daily News, Bullock was forced to call the police after coming face-to-face with Corbett outside her bedroom door in 2014. Bullock said the man believed he was her husband. Later, he detailed plans to sexually assault her.

Police reportedly found machine guns, assault rifles and explosive devices at Corbett's home.
