REPORT: DC Police Set To Announce Arrest In Shooting Of Commanders RB Brian Robinson

ESPN's Montee said the young man has been charged with assault with intent to rob while armed. Since the suspect is a juvenile, Contee would not provide his name or any details of his legal history.

Robinson, 23, was shot twice in the right leg on Aug. 28 near a lively strip of clubs, bars and restaurants along H Street in northeast Washington.

Cops added they are still on the hunt for an additional suspect ... who they say was captured on surveillance video brandishing a gun at the scene of the crime.

As we reported, Robinson was shot two times -- once in the glute and once in the knee -- after cops say two males attempted to rob him outside of a row of businesses in D.C.

Police are offering a reward of up to $10,000 to anyone who can provide information that leads to the arrest and conviction of the person or persons responsible for the crime.

As mentioned, Robinson was shot twice in the leg just before the start of the regular season, but through rigorous effort in rehab, he is back on the field for the Commanders. He made his NFL debut Oct. 9, a little over a month after the crime.
