Calgary police lay dozens of charges in grocery store robberies

CALGARY - Police in Calgary have laid dozens of charges against several individuals in a string of grocery store robberies last fall.

Police allege that a suspect orchestrated the take-over style robberies by enlisting the help of associates.

Investigators say two to four culprits would enter the stores at closing time and order employees to open the safe.

The suspects, who were disguised and armed with guns and knives, would first rob staff and then take off with the safe's contents.

In one case, a store manager was kidnapped, but he was let go uninjured.

A number of the accused have already pleaded guilty and have been sentenced to prison time.
