Police said two would-be robbers were arrested early Sunday morning in the parking lot of a Swiss Chalet restaurant in Ajax, Ontario (just east of Toronto), after spending more than half-an-hour trying to open a safe they had stolen from the restaurant by driving back and forth over it with a car. The two men, and a third still being sought, police said, forced two cleaners leaving the Swiss Chalet back into the restaurant at gunpoint, then bound them with duct tape, robbed them, and kicked one cleaner in the head. Then they dragged out the restaurant safe, loaded it into the trunk of one of the cleaners cars and headed out. Thats when they hit the speed bump in the restaurant parking lot. Out tumbled the safe. What to do? They decided the safe would open if they drove over it with the car. They did. If didnt. The frustrated robbers tried again. And again. And again. Damage to the car was extensive but the safe was barely harmed. A half-hour later, one of the cleaners finally freed himself and called 911. When the police showed up, the men were still busy in the parking lot with the reluctant safe. Police dogs ran down two suspects aged 18 and 19, who face a variety of charges. Police are still looking for a 21-year-old male suspect.
