On the day her father is to be sentenced for assault, police say they're looking into a reported sighting of missing Toronto teen Mariam Makhniashvili.
Vakhtang Makhniashvili pleaded guilty earlier this year to three counts of aggravated assault. The charges followed two separate stabbing incidents last year.
Mariam Makhniashvili vanished in September 2009 and the only clue ever found was the then 17-year-old's backpack.
A police spokeswoman says investigators are looking into a reported sighting of Mariam earlier this week in Toronto.
Const. Wendy Drummond says police are going through surveillance video but can't confirm it was Mariam.
Const. Drummond says police are constantly getting tips in the case and encourage the public to report any possible sightings of Mariam.
