Police at 53 Division have issued a neighborhood alert about break-ins in the Glenvale Blvd area of Leaside (north of Eglinton and South of Sunnybrook Hospital) and in the area between Yonge and Bathurst Sts. near Roselawn Ave. This appears to be a case of thieves assessing homes by knocking on doors to see if anyone is home.Police recommend that if unknown people come to your door to turn on a light and speak to them only through the door (without opening it) to send them away. This, as the police say, makes it clear there is someone home. They also advise homeowners to lock and secure doors and to employ a security alarm.
