Authorities are investigating a three-alarm business fire in Maple Grove Monday night.

According to Maple Grove Fire Chief Tim Bush, crews were called to a business on the 7400 block of Kilmer Lane around 6 p.m. for a report of a printing press on fire.

When firefighters arrived, they found activated sprinklers and visible flames.

A second alarm was then called to bring more stations into service. Although the fire was contained, authorities say the amount of smoke caused ventilation and visibility challenges.

A third alarm was then called to help with overhaul and final extinguishment, Bush says.

Bush adds no one was injured, and the cause is being investigated.
