Qianying Zhao, 23, of nearby Doraville was found at the home shortly after 5 p.m. Wednesday and charged with criminal trespass, Sandy Springs police said. The house is owned by music producer Dallas Austin and is being rented by Bieber, police said. Ashley Austin, 20, lives there and came home to find Zhao in one of the bedrooms.
"Austin said that she did not know Zhao, and had no idea how she got into her house," the report states.
Police say Zhao told officers that she claimed to be a friend of Bieber's, and had entered through an unlocked door of the home on Northside Drive, just north of Atlanta. No one was home.
"She said that she met him on the Internet 'Twitter' and was visiting him for a birthday party," the police report states. "She realized that she was too late for the party, so she decided to wait there for him."
Police say Bieber's party had been held earlier in the week at another place.
Zhao was handcuffed and taken to an Alpharetta jail. It wasn't immediately known whether she has an attorney.
It was the second time in just over a week that police have responded to a problem related to the pop star.
