Longmont police and fire investigators will be on scene at Target today to determine the cause of an early morning fire.

Longmont Fire Department spokeswoman Molly Cropp said the store will be closed for at least a few days as officials work to find the cause and origin.

A structure fire was reported at the store at 551 S. Hover St. at 4 a.m. today.

Firefighters found the store filled with smoke, but Cropp said the store’s sprinkler system put out the majority of the fire before they arrived on scene.

No employees or firefighters were injured during the incident.
