(Reuters) – Five people suspected of shooting at police officers before barricading themselves inside a vehicle in Washington D.C. were arrested on Tuesday, police said.

No one was reported injured in the incident, which took place days after five police officers were fatally shot during a demonstration in Dallas to protest at police violence against black men and other minorities.

In the incident in Washington D.C., officers in marked patrol cars were responding to reports of gunshots just after midnight in the southeast of the city when at least one person inside a parked SUV opened fire on the patrol cars, a spokeswoman with the Metropolitan Police Department said.

The officers returned fire, the spokeswoman said, and the five suspects – three women and two men – hid inside the vehicle during a 30-minute standoff before surrendering.

It was not immediately clear why the suspects fired at police or what criminal charges they might face.
