Toronto police are seeking two suspects they believe are connected to a string of robberies in the west and north ends of the city. 

Police say the pair target high-end vehicles in well off neighborhoods by entering the garages of the homes, disabling the alarms and ransacking the residences looking for the vehicle keys.  In some cases they left with I-Pads and jewellery when they couldn't find the keys. 

Investigators say the suspects got away with 23 vehicles in total including Porsches, Mazarattis and BMWs.  Only 3 vehicles have been recovered.

Officers say they fear that a possible confrontation between a homeowner and the suspect as some were robbed while they slept.  Other homeowners were on vacation when they were robbed.

"[I want] to ensure that the people I these neighborhoods are vigilant [and] looking for suspicious vehicles and suspicious people that are targeting these areas.  These individuals are no doubt around in the daytime or early hours of the evening when it's still light out looking for these type of vehicles.  They are targeting these homes for the vehicles." said Staff Inspector Mike Earl.

Investigators are also telling homeowners to keep their car keys and valuables out of sight.
