US police arrested 22-year-old Robert E Crimo after he was named as a person of interest in the mass shooting that left at least six people dead and 36 injured during a 4 July parade in Illinois.
Mr Crimo was taken into custody after a brief chase near Lake Forest, a Chicago suburb, about six miles from the site of the massacre a few hours.
A video by the Chicago affiliate of ABC News showed the police surrounding a car and then Crimo exiting the vehicle with his hands raised, said a Reuters report. Crimo is then seen lying flat on the ground before police take him into custody.
A video shared online by journalist John Dodge showed armed police persuading Crimo to surrender. “Do me a favour, get on your knees, get on your knees lay down flat on your stomach,” an officer is seen telling the suspect via a loudspeaker.
The arrest came nearly eight hours after the shooting, reported Chicago-based newspaper Chicago Tribune. Crimo was identified as a person of interest by Highland Park police Chief Lou Jogmen.
Crimo was believed to be driving a 2010 silver Honda Fit and was spotted by North Chicago police near US Highway 41 and Buckley Road.
The officer tried to stop Crimo, but he briefly fled before being stopped, the newspaper report said, quoting Jogmen.
