Two Brampton men are charged, and a third man from Windsor is wanted, in connection with a series of "vicious and targeted" home invasions and jewelry store robberies late last year, according to Peel Regional Police.

Police arrested a 32-year-old Brampton resident for four separate incidents that include two home invasions in Brampton, a home invasion in Toronto and the robbery of a currency exchange business.

In two of the incidents, the homes of two South Asian families who own jewelry stores in Brampton were violently broken into, police said. All of the residents, including children and senior citizens, were tied up with zipties and duct tape at gunpoint, Acting Insp. Donny Ross told a news conference on Wednesday.

"Our victims continue suffering," Ross said. "Their families were traumatized in their homes and it was very severe."

Investigators believe that the suspects used GPS trackers on the victims' vehicles to track where they live in order to break in, rob them and get the codes to access the families' jewelry stores.

Police allege the suspects then broke into the jewelry stores on Airport Road in Brampton. The first of the two robberies happened in early November 2015, and the second robbery occurred on December 23.

Police are looking for Rashid Ahmad, 25, in connection with the robbery of a currency exchange on Oct. 31, 2015. Police believe he might be in Windsor. (Peel Regional Police) The second suspect, a 20-year-old Brampton man, has only been charged in connection with one of the robberies.

"We're experiencing throughout the GTA certainly a surge in the number of violent crimes and robberies that have occurred," Ross said, adding that Peel's central robbery bureau's cases are up 65 per cent from last year.

Police are still looking for a third suspect in connection with the currency exchange robbery. The suspects in that robbery wore masks, according to investigators. The 25-year-old Windsor man is described as South Asian, stands about five-foot-nine-inches tall, weighs 157 pounds and has black hair, brown eyes and a scar over his left eyebrow.
