The Capitol Police in Washington arrested an 18-year-old man who jumped out of a car parked near the US Congress building and rushed towards it, armed with a firearm, the Associated Press reported.
The chief of the Capitol Police said that the motives for the actions of the detained person are still being clarified and it is being checked whether there are specific congressmen who were targeted by the attack.
The legislature was not in session at the time of the incident.
