A third police officer who fought thousands of Capitol rioters in Washington has died by suicide.

The family of DC Metropolitan Officer Gunther Hashida announced that he died on July 29 on a GoFundMe page.

It's unclear how the 43-year-old killed himself and his family have not attributed his death to the riot on January 6.

He leaves behind a wife and three children.

A post written by his sister-on-law on the GoFundMe page reads: "On July 29, 2021, we lost Gunther Hashida, who leaves behind a loving wife, sister, 3 children, and a wonderful family.

"In his work as an officer with the DC Metropolitan Police Department, he worked to serve and protect the public. He was a devoted and loving husband and father.

"This fund will help support his memorial service and his family in the loss of his love and guidance."

It has raised more then $19,000 of its $50,000 target.

The dad-of-three graduated from police academy in 2003.

The police department confirmed his death saying he was found a home, but did not give any detail on what contributed to his death.

"Officer Hashida joined MPD in May 2003.

"We are grieving as a Department as our thoughts and prayers are with Officer Hashida’s family and friends."

A woman was shot dead by police during clashes inside the Capitol building and three others were reported to have died.

The historic building was forced into lockdown and the National Guard had to be called in to restore order.

A further three people died of separate "medical emergencies" on the Capitol grounds while police have made 52 arrests.

An Improvised Explosive Device (IED) was also found on the grounds of the US Capitol, as President-elect Joe Biden described the horrifying scenes as an "insurrection".

Capitol Police officer Howard Liebengood killed himself three days after the riot on January 6 followed by DC Police Officer Jeffrey Smith who shot himself on his way to work on January 15.

The grieving widow of DC Smith said he was not the 'same' in the days after the riot.

Erin told The New York Times: "When my husband left for work that day, he was the Jeff that I knew.

"When he returned after experiencing the event, being hit in the head, he was a completely different person.

"I do believe if he did not go to work that day, he would be here and we would not be having this conversation."
