A gang member who had videos taken of himself robbing and beating two people in north Minneapolis was sentenced this week to eight years in prison.

Alan D. Gaines, 21, of Brooklyn Center, known by the nickname "Nasty," pleaded guilty to felony aiding and abetting aggravated robbery of a man and woman in November.

One of the videos, found on Gaines' cellphone by police, was shown to Hennepin County Judge Dan Mabley as part of a victim impact statement before sentencing Wednesday.

According to the criminal complaints and testimony in the guilty plea hearing, police received a request around 6 p.m. Nov. 9 to check on someone last seen in the 5100 block of Fremont Avenue N. in Minneapolis. At the same time, police received a report of a robbery that had occurred in the same area.

Nine days later, a woman was assaulted and robbed by a group.

She initially agreed to go to Albertville, Minn., with a man she knew, but was taken to an alley, again near the 5100 block of Fremont. Attackers came up to the car and kicked, punched and cut the victim with scissors. They took her purse, boots and cellphone.

During her assault, Gaines and another man videotaped and encouraged the fight. The victim moved to the back of the car and locked the doors, but Gaines and others opened the doors and resumed the beating. The victim was taken to North Memorial Medical Center in Robbinsdale, where she was treated for injuries to her eyes, face and hand.

She knew several of her attackers, including Gaines. Police also saw a video of the attack posted on Facebook. Police made several arrests and confiscated Gaines' phone, which had videos of the man attacked Nov. 9.

During the video of the man being beaten and robbed, the attackers refer to "Nasty" and "Kickadoe." They yelled at the victim and told him to "be smarter." Gaines is seen rifling through the victim's pants and taking the money. At one point, the man is lifted off his feet and slammed to the concrete, banging his head.

Gaines is associated with the Kickadoe gang, which police learned through photographs of Gaines displaying gang signs. Those photos were on a phone belonging to a woman involved in the Nov. 18 robbery.

Several others have been arrested in connection with the assaults.
