Two teenagers suspected of killing a congressional intern in Washington DC have been arrested.

Eric Tarpinian-Jachym, a university student who was working in the role in the capital, was shot dead while on his way to McDonald’s on the night of June 30.

A female bystander was injured in the drive-by shooting, which took place between the suspects and a 16-year-old, who was also injured, officials said. It was not clear if the 16-year-old was armed.
