A pair of brothers each received 10 years in jail Sept. 21 for their roles in a string of armed robberies of Washington D.C. taxi drivers last year, the U.S. Attorney for the District of Columbia said.

Darrius Watts, 20, and his brother Gregory Watts, 19, pleaded guilty in July to two counts of armed robbery in connection with incidents which occurred on Sept. 3 and Sept. 6, 2011. The brothers were believed to have been responsible for as many as eight armed robberies of taxi drivers, but with the guilty pleas saw charges against them for the other incidents dropped.

According to a statement from the office of U.S. Attorney Ronald Machen Jr., the brothers had each driver give them rides around the Southwest Waterfront area before luring the driver to secluded streets near the 200 block of G Street SW. Robbing the drivers at gunpoint, the brothers took hundreds of dollars in cash and credit cards.

In announcing the sentence, Machen praised the work of the Metropolitan Police Department, as well as criminal investigators and assistant U.S. attorneys from his office who assisted in trial preparation and sentencing.
