A male juvenile has been arrested in connection with four robberies in the Capitol Hill neighborhood, including three that took place within a four-hour span, D.C. police said.

The first robbery took place Jan. 14 in the 700 block of Eighth Street SE. In that incident, a male victim was getting into his car when the robber approached him and implied that he had a weapon. He demanded property and fled on foot after obtaining it.

The other three robberies all took place Jan. 23.

According to police:

The first of those happened at about 4:40 p.m. that day at the corner of 11th and E streets NE. The youth ran up to the victim in that incident from behind with a knife in his hand. He then demanded the victim's money and cell phone, and he fled with the latter.

At about 6 p.m. that day, the boy ran up to someone who was walking home in the 800 block of Maryland Avenue NE. The robber implied that he had a weapon, demanded property and obtained money from the victim.

Then, about two hours after that robbery, the boy ran up from behind and snatched someone's cell phone in the 300 block of A Street SE.
