TORONTO (AP) ― Investigators arrested a 29-year-old man Wednesday in connection with the death of a student from Beijing, who was last seen alive on a webcam by her boyfriend in China as she struggled with an attacker, police said.

Brian Dickson has been charged with first-degree murder, Toronto police spokesman Tony Vella told The Associated Press on Wednesday.

Dickson is scheduled to appear in court Thursday morning.

Police said the body of York University student Liu Qian, 23, was found Friday in her apartment in Toronto a few hours after her boyfriend in China witnessed the attack. She was naked from the waist down and there were no obvious signs of sexual assault or trauma that would have led to her death.

Liu was chatting with her boyfriend, Meng Xianchao, by webcam at about 1 a.m. Friday when a man knocked on the door, police said.

Meng reported seeing a struggle break out between the two before Liu’s webcam was shut off. The friend contacted other friends in Toronto who in turn called police.
