A fourth person was arrested Monday evening in connection with a June 30 assault and robbery on the 100 block of South Seventh Street in which one of two victims suffered severe injuries.
Benjamin Ellis Nielsen, 22, was arrested on charges of first- and second-degree assault and robbery.
Nielsen was booked into the Boone County Jail on Monday evening and was being held on $50,000 bond.
A video obtained from a nearby business shows Nielsen; Emory J. Montie, 23; Kyle Lee Johnson, 23; and Alexander Edward Nolan, 19, assaulting two people who had approached them on Seventh Street at about 2 a.m., according to a probable cause statement written by police officer Brian J. Grove.
Grove wrote that a few seconds into their conversation, Nielsen is allegedly seen on the video grabbing and punching one of the victims, who was then shoved to the ground by Johnson and Nolan.
Montie allegedly punched a second victim in the face. That victim appeared to lie unconscious on the ground, according to the probable cause statement.
Nielsen and the other three suspects allegedly began hitting, kicking and stomping the second victim for several seconds while he was on the ground. Nielsen then returned to the first victim, kicked him in the head then punched him in the head repeatedly. He then kicked the second victim several times while he remained on the ground.
The victims reported that a necklace was stolen during the assault.
The video shows all four suspects walking away from the scene. Nolan, however, allegedly returned one more time to kick both victims in the head, according to the probable cause statement.
Grove wrote that one of the victims suffered injuries serious enough to require a long hospital stay and perhaps physical therapy. The other victim was treated and released on the day of the assault.
