An early morning blaze that ripped through a Deli in Minneapolis on April 25 sent smoke into a nearby hospital's ventilation system.
The fire was reported around 3 a.m. in the 2500 block of Chicago Avenue South and it quickly escalated to two alarms.
Firefighters used ladder pipes and portable master streams to bring the fire under control in two hours.
The fire generated heavy smoke which travelled into the ventilaton system of a nearby hosptial. Crews there were forced to shut the system down until the smoke lifted from the blaze.
