Three Maryland men were arrested Saturday in connection with an early morning robbery in Adams Morgan. One of the men is charged in a second robbery that police say occurred minutes earlier in the Northwest D.C. neighborhood.

Just after 3 a.m., Sterling Thornton, 22, of Capitol Heights approached an Alexandria man in the 1900 block of Calvert Street, NW, and demanded his watch, a D.C. police spokesman said Saturday. The man refused, and Thornton began striking him in the face and body, according to police.

Moments later in the 1800 block of Adams Mill Road, police said, Thornton and two other men — Montero Valentine, 21, of Capitol Heights and Michael Richards, 21, of Landover — came up behind a man from the Bronx, N.Y., and began punching him. The three men are accused of taking his watch and iPhone.

D.C. police spokesman Officer Araz Alali said police arrived quickly and apprehended the three men, who were all charged with robbery by force. Thornton was also charged with assault with intent to rob, police said, after he was identified by the first victim.
