A man arrested in Sandra Bullock’s Los Angeles home was inside for more than an hour while she slept.

Joshua James Corbett, 39, scaled a barbed wire fence and entered her home at 5am on Sunday morning, according to a report by CNN.

Los Angeles police said they were not called until 6.30am, suggesting that Bullock was asleep while Corbett spent more than an hour inside her house.

The man was also found to be in possession of an illegal machine gun, but did not have it with him when he allegedly broke into the actress’ home.

Corbett entered a not guilty plea but was charged with residential burglary, stalking and possession of a machine gun.

It is unknown if Bullock’s young son was also at home during the time of the break in.
