The 18-year-old man shot by police after he allegedly opened fire during a protest in Ferguson, Missouri, Sunday night was out on bond in a separate felony case, KTVI-TV reported.

A St. Louis Police Department spokesman confirmed to TheBlaze that Tyrone Harris Jr. was arrested in November on charges of stealing a car, theft of a firearm and resisting arrest by fleeing.

According to KTVI, police had pursued Harris speeding down a one-way street. After officers threw down stop sticks and arrested him, he reportedly admitted to stealing the car as well as a 9 mm gun.

KTVI also reported that a Facebook page said to belong to Harris features dozens of photos of Harris posing with guns and statuses about illegal and gang-related activities, often using the hashtag #pistolgang.

The following are images KTVI and the website the Daily Haze attributed to Harris’ Facebook page, where he went by “Ty Glocks.” The St. Louis police spokesman could not confirm the authenticity of the page, as it is unrelated to his pending case.

According to KTVI, Harris’ last Facebook post said, “I f*** around go on West Florissant tonight.”

Police say Harris opened fire on plainclothes officers Sunday night after spotting their unmarked van with police lights. Officers returned fire, striking Harris, who was taken to the hospital and remains in critical, unstable condition.

St. Louis County Police Chief Jon Belmar said there was “a remarkable amount of gunfire.”

Harris will be charged with 10 felonies, including first-degree assault on law enforcement officers, according to KTVI.

After the shooting, police said Harris was carrying a stolen 9 mm.

Harris’ father told the St. Louis Post-Dispatch that Harris was “real close” to Michael Brown, who was fatally shot one year ago in a confrontation with a white police officer.
