A man detained by officers and sent to the hospital died on Thanksgiving after people reported the man yelling and running in the streets, the Portland Police Bureau said in a press release.

Portland State University police responded to calls about the man around 8:19 p.m. and located him near Southwest 6th Avenue and Southwest Mill Street. They called the Portland Police Bureau for backup after a struggle with the man, the release says.

Officers restrained the man, who police identified Friday night as 52-year-old Richard A. Barry, and called for an ambulance "based on his behavior." Recent records show Barry listed his address as a homeless housing shelter downtown.

"At this time investigators believe the man suffered a medical event and died while receiving treatment at a Portland hospital," the Portland Police Bureau release says.

During the struggle, a Portland State police officer was injured, according to a statement from the university. The nature of the officer's injury was not stated but the officer was treated at the hospital and released.

Homicide detectives along with the bureau's professional standards division are investigating the incident, the results of which will be reviewed by the Multnomah County District Attorney. An internal review will also go before the Police Review Board.

The Oregon State Medical Examiner's Office on Friday began an autopsy on Barry to determine the cause of death, police said. Police did not know when the autopsy investigation would be complete.

The two Portland police officers who responded are on paid administrative leave, per policy, while the investigation is underway. They were identified Friday night as Officers James DeAnda, a 1-year veteran of the bureau, and Jared Abby, who joined the force 11 months ago, authorities said.

The four campus police officers who responded are also on paid leave per policy and the university is cooperating with the investigation, according to the university. They have not been identified.

Portland State police were involved in another death earlier this year. In that matter, police shot and killed a 45-year-old Navy veteran who was visibly armed while trying to break up a fight, according to witnesses.
