A man was arrested Friday after he allegedly threatened his ex-girlfriend's father with a handgun.
Matthew Marzolf, 23, of Rapid City walked into American Lawn Mower on East St. Patrick Street around 4:50 p.m. Friday and while arguing with the man pulled a revolver, according to police spokeswoman Tarah Heupel.
After Marzolf left the business, police found him getting a haircut at an East St. Patrick Street salon. He was charged with aggravated assault, driving with a suspended license and possession of a concealed weapon without a permit. He is being held in the Pennington County Jail under a $7,500 bond.
