Two firefighters were attacked by an "erratic" individual in Anoka County on Wednesday.
The sheriff's office says its deputies joined the Linwood Fire Department in responding to an RV on fire at 213th Avenue Northeast in Linwood around 6:15 p.m.
But after extinguishing the RV fire, a 39-year-old man approached two firefighters with a blunt object in each hand and began attacking them, striking them in the head and face.
After the attack, the man – described by police as acting in an "erratic manner" – ran back into the house at that address, and set it on fire.
He then climbed onto the roof of the building while holding a knife, which he refused to surrender, and only dropped it after being hit by less-lethal bean bag rounds by police.
He stay on the roof though, police said, even though it had started to collapse "due to the raging fire beneath it."
He eventually jumped off and tried to escape, but was captured.
The suspect is believed to have been staying at the house, which is owned by one of his relatives.
He has been booked into Anoka County Jail for assault and arson, but has not yet been charged.
