Authorities have yet to confirm whether the officer in that video was Sicknick, who died Thursday night after being hit in the head by a fire extinguisher when he and his colleagues faced hundreds of Donald Trump supporters who died on Thursday night Stormed the Capitol the day before.

A wider excerpt from the video shows a man walking towards the group of police officers with a fire extinguisher in hand
DailyMail.com posted the disturbing video MondayMail of a MAGA rioter throwing a fire extinguisher into a group of Capitol police officers.
At the beginning of the two-minute clip, a fire extinguisher lies on the floor as dozens of police officers battle a crowd of Trump supporters who storm towards the Capitol building to prevent Congress from confirming Joe Biden's election.
A protester picks up the fire extinguisher and walks towards a crowd of fellow rioters who bump into police officers.
The video shows another demonstrator pushing an officer off the edge of the building – before the man with the fire extinguisher comes out of nowhere and fires it at the police station. It ricochets off one officer's helmet before hitting another who falls backwards. He seems to find his balance easily again before the clip cuts off.
Last week, authorities announced that Sicknick had died from injuries sustained during the riot – including a headbutt from a fire extinguisher.
Sicknick managed to move away from hand-to-hand combat before collapsing in his departmental office hours later. He was hospitalized and given life support before being pronounced dead the following night.

According to the Department of Justice, since the siege of the U.S. Capitol, which according to the Department of Justice lost five people, at least 20 people have been indicted in the federal district court in Washington DC and another 40 people have been tried in the local Supreme Court.
Investigators comb social media images showing hundreds of people swarming the building, attacking the police, stealing computers and artifacts, and breaking windows.
Sicknick had wanted to be a police officer since childhood in a hamlet in New Jersey. He joined the National Guard six months after graduating from high school in 1997
The US Attorney's Office in Washington, with the assistance of the FBI, the DC Metropolitan Police Department, and the Capitol Police, is leading the federal investigation into Sicknick's murder.
In a statement, Acting Attorney General Jeffrey Rosen said the Justice Department would "not save resources on investigation and accountability of those responsible".
Sicknick's family released a heartbreaking statement Monday remembering him as a "lovable, humble soul" who had always wanted to be a police officer and was "very passionate" about his job.
“There really aren't enough nice words in any language to describe how cute Brian was. He really was a beautiful, humble soul. We miss him terribly, ”was the explanation.
& # 39; He was gracious through and through. Everyone who met him adored him. He was also very fond of his Dachshunds, pampering them and making sure they received the best possible care.
& # 39; He also had an incredible work ethic. He was very serious about getting to work on time and refused to call sick unless it was absolutely necessary.
& # 39; Our loss of Brian will leave a huge hole in our hearts. The tremendous support we have received from the US Capitol Police, the law enforcement community, and the entire community has been overwhelmingly warm and generous. We are very grateful for everyone's kindness during this difficult time. "
Sicknick has wanted to be a police officer since childhood in a hamlet in New Jersey, his family said.
He joined the National Guard six months after graduating from high school in 1997 and posted to Saudi Arabia and then to Kyrgyzstan. He joined the Capitol Police in 2008.
Pro-Trump insurgents stormed Capitol Hill on Wednesday in an attack that stunned the nation
The FBI had arrested another person in New York yesterday in connection with the riot.
An FBI spokeswoman said agents had arrested Aaron Mostofsky, whom several news outlets identified as the son of New York Supreme Court Justice Shlomo Mostofsky.
Mostofsky's presence at the Capitol was quoted in a New York Post article identifying him as the judge's son.
The article also included a video of Mostofsky in a fur costume at the Capitol.
The Post quoted him in an interview as saying, “We have been betrayed. I don't think 75 million people voted for Trump – I think it was almost 85 million. & # 39;
In a criminal complaint published Tuesday, the Justice Department accused Mostofsky of stealing state property, illegally entering the country, knowingly interfering with government business and acting disorderly.
The complaint, citing the New York Post reporting, said he was photographed with a US Capitol Police sign and a police vest, both valued at more than $ 2,000.
He is due to appear in federal court in Brooklyn on Tuesday.
Two other suspects are due to appear in various federal courts Tuesday, including one arrested after Molotov cocktails were found in his truck and another photographed at the desk of a staff member for House Spokeswoman Nancy Pelosi.
Acting US attorney Michael Sherwin also issued a statement on Tuesday calling on media representatives attacked or threatened during the riot to contact his office for details.
"We are determined to uphold the freedoms guaranteed by the First Amendment, including speech, peaceful gathering and press, and we will investigate, prosecute and hold accountable anyone who attempts to obstruct or limit these freedoms through violence or intimidation "said he said.
