Responding to community concerns about a rising number of street robberies, District police late Friday announced arrests in three recent cases.

Police arrested a man in an armed robbery from the night of April 5 that began when the robber asked the victim for a ride. According to police, the man showed a knife and demanded the victim’s property after being picked up in the 1800 block of Providence Street NE, not far from New York Avenue.

In the second case, police arrested one man and are looking for two others in a robbery that occurred Tuesday about 10:15 p.m. near the Verizon Center in the 600 block of F Street NW. The victim told police that his cellphone was stolen when three men assaulted him.

Police have also made an arrest in a third robbery, committed Wednesday. The victim reported that a woman snatched cash from her hand just after 10 p.m. in the 300 block of Pennsylvania Avenue SE.

Officer Paul Metcalf, a police spokesman, said Saturday that D.C. regulations prohibit the department from publicly releasing the names of those arrested after a certain period.

Even though the District’s overall crime rate has declined in recent years, robberies — along with sexual assaults and thefts — have increased, raising concerns across the city.
