Update, May 2, 2:50 pm:

SPOKANE, Wash. - Court documents obtained by KHQ have shed more light on a video showing a man lighting a Molotov cocktail amid the chaos of Sunday's riots in downtown Spokane. 

According to the documents, law enforcement was alerted to the video when it was posted on KHQ.com. The next day, Spokane Police Department Dispatch received information from the Kootenai County Sheriff's Office identifying the suspect as Gene Gallagher. 

An anonymous tipster had also contacted police to identify Gallagher. The tipster said he called Gallagher and confronted him about his actions and Gallagher confessed to throwing the Molotov cocktail. According to the documents, he told the tipster that he got caught up in the emotion of the situation. 

At approximately 9:00 p.m. on Monday, Gallagher was taken into custody in the area of Main and Stevens in downtown Spokane. According to the documents, he had a lime green right-handed glove in the front pouch of his jacket that matched the one worn in the video. 

Officers also searched a backpack Gallagher had been carrying and found two lighters and an open bag of Maxi-pads. One of the pads had reportedly been formed into a cylinder shape consistent with having been stuffed into an alcohol bottle. 

Officers also found a secret compartment in the rim-liner of Gallagher's hat containing a small baggie  with a light-colored powdery substance. The substance tested positive for opiates and appeared to be heroin. 

According to the documents, Gallagher did not want to make a statement or answer any questions before he was booked into jail for a second-degree charge of incendiary device.

SPOKANE, Wash. - Sunday night went from peaceful protests about the death of a black man in police custody, to riots and looting, with many of the original protesters working to stop the violence.

In the midst of Sunday night's chaos, KHQ's Help Me Hayley received a video from a viewer that appears to show a man lighting a Molotov Cocktail, a type of crude bomb used by rioters. The video cuts out as he lights fire to the device, but the viewer says the man throws it toward police.

KHQ exclusively reported the story Monday as multiple agencies were looking for that man, but did not know who he was. According to investigators, an Idaho law enforcement officer was among the many thousands who saw our story and recognized him as Gene Gallagher. Social media comments on our story also identified the man as Gene Gallagher. Spokane police officers moved in and arrested him Monday night. Gallagher was charged with Possessing an Incendiary Device (a device designed to cause fires), 2nd Degree Assault, and Possession of a Controlled Substance.
