A northern Minnesota man is being held at the Chisago County jail on suspicion of second degree arson, KARE 11 reports. North Branch police arrested the 21-year-old in connection with an arson fire that nearly destroyed the North Branch Veterinary Hospital earlier this month.

Shakopee fire investigators are suspecting the fire and explosion that gutted a wine and spirits store in the city early Friday is arson, KARE 11 reported. No one was injured, but the blast blew out the front windows of the Wine Styles beverage store and caused some structural damage.

Arson is the suspected cause of a fire Thursday that caused $750,000 in damages and all but destroyed an old wooden bridge that spanned the Pike River in northeastern Minnesota, authorities say. Located about 15 miles northeast of Virginia, the bridge was on a road that saw little traffic -- but without it, a fire chief says, there could be delayed response times for emergency vehicles.

Firefighters are still trying to determine the cause of a massive fire that destroyed the historic Swany White flour mill in Freeport, Minn. The entire structure collapsed as bystanders filled the streets of the Central Minnesota town to watch the blaze, which could be seen for miles.
