On Thursday, at around 9:30 PM, officer Brian D Sicknick died ‘due to injuries sustained while on duty,’ US Capitol Police said in a statement.

Sicknick’s demise brings the total casualty of the riots up to five after a demonstrator was shot in the neck while entering the building, and three others died after separate medical emergencies.

“Officer Sicknick was responding to the riots on Wednesday, January 6, 2021, at the US Capitol and was injured while physically engaging with protesters. He returned to his division office and collapsed. He was taken to a local hospital where he succumbed to his injuries,” the statement reads.

The events that happened on Wednesday saw hundreds of the Trump supporters breaking into the Capitol, many of them armed with different weapons, with a number of explosives reportedly found on site.

Lawmakers and government officials were forced to leave the building, delaying the official certification of President-elect Joe Biden’s Electoral College victory.

The mob was in the Capitol building for around 90 minutes.

Another Capitol Police officer, Chief Steven Sund, has announced he’s handing in his resignation following the events that saw officers being ‘actively attacked’ by rioters, who were armed with metal pipes and other weapons.

“They were determined to enter into the Capitol Building by causing great damage,” Sund told CNN. “The violent attack on the US Capitol was unlike any I have ever experienced in my 30 years in law enforcement here in Washington DC. Maintaining public safety in an open environment, specifically for First Amendment activities, has long been a challenge.”

There has been a lot of anger and criticism from the public over the different responses of law enforcement during the riot, with people comparing the police’s response to the Black Lives Matter protests back in 2020.

Even a number of lawmakers have been baffled over the lack of preparation, given that Trump had made no secret of his plans to encourage supports to protest in an effort to try and block the certification of Biden’s win.
