"There were 68 arrested yesterday evening into the early morning hours of January 7. Of the 68 arrests, 60 were adult males and eight were adult females. Forty-one of those arrests occurred on US Capitol grounds and, to my knowledge, only one of the arrestees is from the District of Columbia," Contee said during a press briefing.
Contee vowed to identify and hold "each and every one of the violent mob" accountable for their actions and asked the public for assistance.
"We still have a significant amount of work ahead of us... We have collected numerous images of interest that we are asking the community to help us identify," he said.
Contee added that 56 police officers were injured in clashes with supporters of President Donald Trump who broke into Congress in an attempt to disrupt the certification of results of 2020 election winner Joe Biden.
