Four people died and 52 were arrested, Washington D.C.’s police chief said, after supporters of President Donald Trump stormed the U.S. Capitol on Wednesday to stop Congress from certifying President-elect Joe Biden’s election victory.

In a late night news conference, Metropolitan Police Department Chief Robert J. Contee said 47 of the 52 arrests to date were related to violations of Mayor Muriel Bowser’s 6 p.m. curfew, with 26 of those involving people arrested on U.S. Capitol grounds.

Several others were arrested on charges related to carrying unlicensed or prohibited firearms.
