The Gainesville Police Department said in a news release Friday that 28-year-old Tyler Tenbrink, 30-year-old William Fears and 28-year-old Colton Fears, all from Texas, were arrested on attempted homicide charges.
Police say the three were in a vehicle Thursday after Spencer's speech and began making Nazi salutes and shouting Hitler chants at a group of people at a bus stop.
Police say Tenbrink showed a handgun while the Fears brothers encouraged him to shoot.
He fired a single shot, police say, missing the group and striking a nearby building.
Police say two of the three have connections to "extremist groups."
