SHOCKING footage shows the dramatic moment a suspected July 4 parade shooter was arrested after allegedly gunning down six.
Six people were shot dead and 30 others were left injured in the holiday tragedy.
Footage shared online shows Crimo being held down and cuffed by police just outside of Chicago.
He was seen with his face on the ground as cops swooped in on him.
The capture comes after the alleged gunman was spotted around 6.30pm local time when officers tried to stop him - but he sped away, prompting a brief pursuit before he came to a stop.
He was taken into custody “without incident" and later charged on Tuesday with seven counts of first-degree murder, according to state attorney Eric Rinehart.

Crimo posted videos on a YouTube channel that has since been terminated due to violating community guidelines.
Several of these videos contained music created by him, along with disturbing videos to accompany the tracks.
In 2019, the amateur rapper's father, Bob Crimo, ran a mayoral campaign in the neighborhood with the slogan, “A Person for the People,” however, he was unsuccessful, reported Fox News.
Gunshots rang out just 10 minutes after the start of a Fourth of July parade in Highland Park, Illinois - about 25 miles north of Chicago - on Monday.
Beach chairs, baby strollers, backpacks, and blankets were found strewn across the parade grounds as revelers sought cover.
Highland police believed the shooter scaled a ladder in an alley to access the roof of a business and then proceeded to open fire at parade-goers.
“He was very discreet and very difficult to see,” Lake County Major Crimes Task Force spokesman Chris Covelli said.
Authorities recovered a "high-powered rifle" believed to have been used in the mass shooting.

"By all means, at this point, this appears to be completely random," Covelli said.
The Lake County coroner's office said five victims, all adults, were declared dead at the scene, while a sixth victim died at a local hospital.
“We are all feeling pretty numb. We’re all pretty broken inside,” his granddaughter told the outlet.
ABC News named Jacki Sundheim as another victim in the tragedy.
First responders transported 23 people to area hospitals plus an unknown number of walk-ins.
Several witnesses told the Chicago-Sun Times that they heard about 20-25 shots fired.
“I heard 20 to 25 shots, which were in rapid succession. So it couldn’t have been just a handgun or a shotgun,” Miles Zaremski told the outlet.
The witness said he saw "people in that area that got shot,” including “a woman covered with blood."
“It was a quiet, peaceful, lovely morning, people were enjoying the parade,” bystander Adrienne Drell told the Chicago-Sun Times.
“Within seconds, to have that peacefulness suddenly ripped apart, it’s scary. You can’t go anywhere, you can’t find peace. I think we are falling apart.”
Witness Zoe Pawelczek told CNN parade-goers initially thought the array of pops were fireworks given the occasion.
"And I was like, something's wrong. I grabbed my dad and started running. All of a sudden, everyone behind us started running," she said.
"I looked back, probably 20 feet away from me, I saw a girl shot and killed.
"I saw her die. I've never seen anything like this."
Pawelczek and her father hid behind a dumpster for about an hour until police moved them into a sporting goods store and then eventually escorted them back to their car, she said.
She saw one person who had been shot in the ear and had blood all over his face and another girl who was shot in the leg.
"It looked like a battle zone, and it's disgusting. It's really disgusting," she said.
RUNNING FOR COVER
Warren Fried, who attended the parade with his wife and seven-year-old twins, said he watched the police and ambulance pass by him at the parade and then heard an array of gunshots.
He said people began yelling "shooter" and "run," and he and his family fled toward their car for safety.
"People were hiding, kids were on the streets looking for their parents, just in a state of shock," Fried told CNN.
The shooting terrorized residents of the wealthy Chicago suburb, where the median home is valued at $535,000 and more than 75 percent of people 25 and over have a college degree, according to US Census data.
BIDEN DENOUNCES GUN VIOLENCE
President Joe Biden said he was left shocked by the "senseless gun violence" that "brought grief" on Independence Day.
The president has pushed for more gun reform since the May 24 shooting in Uvalde, Texas, that killed 21 people - 19 of which were children.
In a statement, Governor JB Pritzker said: “There are no words for the kind of monster who lies in wait and fires into a crowd of families with children celebrating a holiday with their community.
“There are no words for the kind of evil that robs our neighbors of their hopes, their dreams, their futures.
“There are no words I can offer to lift the pain of those they live behind. I will stand firm with Illinoisans and Americans: we must - and we will - end this plague of gun violence.”
Illinois Rep Brad Schneider tweeted that he and his team were gathered at the start of the parade route when the shooting began.
"Hearing of loss of life and others injured," Schneider tweeted.
"My condolences to the family and loved ones; my prayers for the injured and for my community; and my commitment to do everything I can to make our children, our towns, our nation safer. Enough is enough!"
Highland Park's July 4th parade was expected to feature floats, marching bands, novelty groups, community entries, and other special entertainment, the city said on its website.
Nearby suburbs have canceled their Fourth of July parades in the wake of the shooting.
