Deputies responded to the DMV for a report of a disorderly customer. Upon arrival, it was learned that a customer was pulling on a credit card machine, and a security guard hired by the DMV, confronted the customer. As the customer was attempting to leave, the security guard forcibly detained him and began striking the customer with a baton. The customer was transported to a local area hospital for treatment of his injuries. The security guard, Sani Barua, 34 of Alexandria was charged with Unlawful Wounding and transported to the Loudoun County Adult Detention Center where he was released on his own recognizance. This case remains under investigation.
