When it announced on Wednesday that an arrest had been made in a shooting that injured Washington Commanders running back Brian Robinson Jr. on Aug. 28, the Metropolitan Police Department indicated two more suspects were being sought.

On Friday, the Metropolitan Police Department announced another male teen, who had been 14 years old at the time of the incident, had been arrested. The now 15-year-old was charged with assault with intent to rob while armed (gun), the same as the 17-year-old arrested on Wednesday.

On Aug. 28, Robinson was shot in the hip and knee when he was accosted by two armed teens seeking to steal his Dodge Challenger Hellcat in Washington, according to District of Columbia police, who reported the former Alabama standout wrested a gun away from one of the boys before being shot by the other.

After being shot, Robinson was taken to a hospital, where he had surgery before being released the next day.

On Friday, the Washington Post and WJLA-TV reported the 17-year-old charged in the Robinson shooting also had been charged in a deadly shooting on March 25 at the Mall of Prince George’s in Hyattsville, Maryland.

Charged with his twin brother, the teen was not prosecuted because of a lack of evidence, while his brother was indicted on murder charges.

Robinson returned to practice on Oct. 5 and ran for 22 yards on nine carries in his NFL debut on Oct. 9 in Washington’s 21-17 loss to the Tennessee Titans.

Robinson made his first NFL start four days later, when he ran for 60 yards and his first touchdown on 17 carries in a 12-7 victory over the Chicago Bears.

In four games, Robinson has run for 175 yards and one touchdown on 54 carries and caught two passes for 13 yards this season.

“I was just happy they found somebody,” Robinson told WJLA. “I really haven’t been thinking much about it, you know, just been in the locker room, focusing on the season, stuff like that. I was just happy to hear they found somebody, so, you know, that was a relief.”

The Commanders play the Minnesota Vikings at noon CST Sunday at FedEx Field in Landover, Maryland.

A prep standout at Hillcrest-Tuscaloosa, Robinson joined the Commanders in the third round of the NFL Draft on April 29 after running for 1,343 yards and 14 touchdowns and catching 35 passes for 296 yards for Alabama during the 2021 season.
