The St. Louis County Sheriff's Office says a 55-year-old Orr man is behind bars after allegedly robbing the American Bank of the North in Orr Wednesday morning.

Authorities say the man came into the bank around 11:40 a.m. and used pepper spray on two bank employees.

The employees were later taken to a hospital in Cook to be treated for their injuries. 

The suspect left on an ATV, and was spotted by a passerby, who called 911, saying they saw an ATV enter a location just north of Orr.

The Sheriff's Office says they believe he is the only suspect involved. 

He is being held at the Hibbing Jail on charges of aggravated robbery.

No other weapons are believed to have been involved.
