WINDSOR, Ont. -- Tenants were forced out of 11 apartments early Saturday morning after a fire inside a Windsor, Ont., restaurant.

Investigators say the cause of the blaze that broke out at the Tres Bean Coffee House (on Ottawa Street) is undetermined.

The Red Cross helped the displaced tenants but there were no immediate reports of any injuries.

Officials say damage is estimated at $200,000 and the tenants will not be allowed to return to their apartments until utilities are restored.
