Four siblings are in custody, charged in what D.C. police describe as a family crime outing. They are accused of robbing a bank earlier this month in downtown Washington’s Mount Vernon Square.

Authorities said all four participated in one way or another in robbing the Colombo Bank in the 1300 block of 9th Street NW. The incident occurred about 10:40 a.m. on May 15.

Police said that one of the suspects handed a teller a note reading, “Empty Drawer Fast or Everybody Dies!!!” according to court documents filed in the case. Police said the man put a black backpack on the counter as the teller filled it with $800 and a dye pack. The document says the lookout then shouted: “Let’s go! Let’s go! They got us” as they ran out and got into a red compact Chevrolet parked at a gas station across the street.

Authorities said that the dye pack exploded in the bag and that the red-stained money was recovered at the gas station. Police said three of the suspects had been in the bank three days before the robbery and that a teller grew suspicious when the robbery occurred because the men were dressed in winter clothing.

Two of the suspects were arrested Wednesday and the other two Friday, according to Officer Araz Alali, a D.C. police spokesman. All have been charged with bank robbery. Police identified them as: Allante Alexander, 20, of Southeast; Allesha Alexander, 25, of Northeast; Alex Alexander, 20, of Southeast; and Alvin Alexander III, 24, of Southeast.
