Yes, an unfortunate incident at the Dollar Plus store at North Capitol and O St. NW.
There appears to have been an altercation between an employee and another subject in the store. This other subject was very seriously injured and this case is being investigated by our Violent Crimes Branch.
As this is an active investigation, I can’t give too many details at this time, but all culpable parties have been arrested. I will post more details as they are made public,
Acting Lieutenant
Jon Dorrough
Metropolitan Police
Washington, DC
Fifth District
