Police say that on July 11 around 10:30 p.m., 15-20 suspects ambushed three men and one boy near the exit of the Shaw Skate Park on the 1100 block of R Street NW.
The robbers surrounded three of the victims and repeatedly struck them until they surrendered their property, police told Borderstan on July 16.
A video connected to the robbery and released by police earlier this month shows a man forcefully beaten on the ground as he clenches onto a bicycle.
Police have charged the boy with robbery force and violence in connection with the crime.
The investigation is ongoing, say police.
Anyone who has information regarding this case should call police at 202-727-9099. Additionally, information may be submitted to the TEXT TIP LINE by text messaging 50411.
The Metropolitan Police Department currently offers a reward of up to $5,000 to anyone who provides information that leads to the arrest and conviction of the person or persons responsible for a robbery force and violence committed in the District of Columbia.
