The Boston man accused of grabbing a city police officer’s gun and shooting himself in a “high-profile area” near Massachusetts General Hospital is being held without bail pending a dangerousness hearing.

Elvis Haughton, 46, appeared at Boston Municipal Court Central on Wednesday without a court-appointed attorney, a day after he allegedly caused the chaotic scene outside the busy hospital on Cambridge Street.

A group of contracted public defenders has declared they won’t take new clients until they see a pay raise, leaving Haughton on his own during his arraignment. A judge ordered him held without bail pending a dangerousness hearing scheduled for Monday.

Haughton faces charges of assault and battery on a police officer, illegal possession of a firearm, possession of a class C substance, and resisting arrest, according to the Boston Police Department.

The man underwent a mental health evaluation before arraignment, the Suffolk County District Attorney’s Office said in a release. A court clinician did not recommend that Haughton be further evaluated.

“The quick actions of police officers, assisted by bystanders, in a busy area on a busy morning helped ensure that this incident did not result in far worse outcomes for those involved and those nearby,” Suffolk District Attorney Kevin Hayden said in a statement on Wednesday.

BPD Commissioner Michael Cox said Tuesday that Haughton suffered injuries considered not life-threatening after firing a single shot with the officer’s gun. The man “somehow attacked the officer” before he, “in some way, shape or form,” got hold of the gun, Cox said.

A bullet struck the foot of the man whom the police commissioner said was suffering mental health issues at the time of the incident, at about 8:42 a.m. Tuesday.

Eddy Rivera, a Cambridge resident who was working at a nearby restaurant, told WHDH-TV and other reporters that he was one of the bystanders who helped to subdue the man. He heard the gunshot, immediately ran over to help, and noticed an officer in distress, he said.

“I heard a gunshot,” Rivera said. “Cops were across the street and they were yelling out for help so I ran across the street and I jumped on the guy, straddled his chest and then I grabbed his arm.”

Rivera said the man appeared to be a “little disoriented” and “mentally unstable,” and that the broad-daylight gunfire left people in the area “rattled.”

“I heard distress so I thought I’d lend some assistance,” Rivera said.
