Missing Toronto teen Michelle Yu has made contact with her family, a family friend told CP24 Sunday afternoon.

Yu, 18, was last seen in Toronto Tuesday afternoon at about 2:30 p.m. near York Mills Road and Chipstead Road and then at about 6 p.m. when she used her bank card at a TD Bank at 354 Bay St., south of Queen Street West, in downtown Toronto.

Toronto police say that Yu's family has contacted them, telling them that they have been in contact with their daughter who is out west, possibly in British Columbia.

Since the information has not been confirmed, she is still officially missing, police said.

On Friday, Yu's mother made a public plea for her daughter's safe return.

"Michelle, I know you are a good girl and I don't know what happened," Sharon Wu Yu told CP24 following a news conference outside York Mills Collegiate Institute where her daughter is a student. "Do something to say you are safe. That's all I want."

In an interview with CP24 on Thursday, Det. Const. Roger Marchack said Yu appeared to have disappeared of her own free will, but on Friday Yu's mother said it's unlike her daughter to just disappear.

"She is a very normal girl," she told CP24 following the news conference. "She has tons of friends to talk to and she doesn't have any problems. Something is unusual."

Family and friends of Yu had been distributing posters featuring her photo throughout the city and had solicited information about her whereabouts using several social media sites.

On Thursday, Yu's Grade 12 classmates at York Mills Collegiate Institute attended an assembly where they discussed further ways to help locate the missing girl.

"We are very, very concerned and we want to hear from her," Principal Clara Williams told reporters. "We just want to hear that Michelle is safe and if she feels that she cannot come back right now, we want her to call any one of her friends and tell them that she is OK."
