Police are searching for a York University student after she went missing on her 19th birthday last Friday.

​ ​Amina Lawal, a student at York's Schulich School of Business, was reported missing by her mother last Saturday after she didn't return home from a school group meeting on Friday night. Funmiloya Odusola , Lawal's mother, said around 6:30 p.m. her daughter called to say she was on her way home (she would have taken public transit) from the meeting, but never showed up.

"She’s a good girl. She works so hard. She’s a very smart girl … what am I going to do?" Odusola said before breaking down in tears.

"I love you … Come back home. Please," she said.

Odusola said it's "really unusual" for her daughter to lose contact with her and said she's afraid something bad has happened.

Toronto police said they were "concerned" for Lawal's safety in a news release on Monday. Police are still seeking any information about her whereabouts, and on Tuesday, Lawal's family still hasn't heard anything.

Lawal was last seen at home in Scarborough's Kingston Road and Beechgrove Drive area on Friday morning, where she had a birthday breakfast. It's not clear where she went after that, police said.

Lawal stopped attending class: police

43 Division Staff Sgt. Kevin Murrell said police have no specific leads, but have learned from friends and the university that Lawal had stopped going to classes several weeks before her disappearance, something that may help their investigation.

"We also know that there’s some information she may not have been disclosing to mom," Murrell said.

"There might be other things going on in her life that we don't know about," he added.

Murrell said because police don't know who Lawal is with, they cannot rule out foul play, though he said many young people go missing then eventually return home safe.

Odusola said she's hoping her daughter will return soon. She said Lawal and her son are all she has, and that she relies on them both.

Online, those who know Lawal fretted about her whereabouts, frequently posting using the #helpfindamina tag on Twitter.

Lawal is described as being 5'2" and around 100 pounds with long, black hair worn in braids.
