California authorities on Thursday announced that a suspect accused of opening fire on a Greyhound bus Wednesday evening — while naked — has been arrested.

Officials detained Asaahdi Elijah Coleman, 21, on Wednesday evening after he allegedly shot five people, killing at least one, aboard a Greyhound bus at a gas station around 7:30 p.m. PT. 

The other four victims include an 11-year-old girl who remained in stable condition, a 25-year-old pregnant woman who was in critical condition, a 38-year-old man who suffered a minor injury and was in good condition, and a 32-year-old man who suffered multiple wounds and remained in critical condition.

Coleman boarded the bus in Redding, California, took a seat in the back of the bus and made or received a phone call that "appeared to agitate him," Butte County Sheriff Kory Honea said during a Thursday news conference.

Coleman began to talk to other people on the bus and seemed "paranoid" that the bus was headed toward Los Angeles, at which point he showed other passengers a firearm he was carrying. 

Once the bus arrived in Oroville and people began to exit, Coleman allegedly began firing the weapon.

Oroville police arrived at the scene of the crime about a minute after receiving the first reports of a shooting on the bus. With assistance from Butte County sheriff's deputies, they located the victims on the bus and began to offer them aid.

The suspect fled the scene, and authorities eventually located him at a Walmart about a half-mile from the shooting scene in Oroville.

"At that point, he had no clothing on [and] was acting in … an erratic manner," Honea said, adding that the investigation into the shooting was continuing.

Coleman engaged in a verbal dispute with one female Walmart customer, which led to a physical altercation with the customer's boyfriend, the sheriff said. At that moment, Coleman began to remove his clothing before police arrived and took him into custody, the sheriff added.

The suspect was already wanted on a warrant out of Alameda, California, for possession of a firearm from a prohibited person, Butte County District Attorney Michael Ramsey said.

Deputies recovered Coleman's firearm and Justice Department investigators found 12 shell casings inside the bus, according to Ramsey.

Oroville is about 69 miles north of Sacramento.
