Two tourists walking in New Orleans' French Quarter were attacked and mugged Saturday evening and it was all caught on camera.
Police say 21-year-old Dejuan Paul turned himself in.
Police said the attackers made off with the victim's cellphones and wallets.
Michael S. Harrison, superintendent of the New Orleans police, said in a message posted to Twitter that the remaining suspects will be located.
Surveillance footage shows suspects in the attack on two tourists in New Orleans' French Quarter on Saturday, June 24, 2017.
The tourists, identified as James Curran and Tim Byrne of Boston, were leisurely walking through the French Quarter on their way back to their hotel just before 9pm, when they were jumped from behind and then robbed by four men.
Roger Federer moves into 140th career final at Halle
The 20-year-old Zverev had no answer to Federer's inch-perfect execution and was broken three times in a lightning-fast first set. Zverev defeated Federer a year ago in a three-set semifinal and they could meet again in the final.
New Orleans Police Officer Juan Barnes Sr. says the siblings were arguing from their cars in the Little Woods neighborhood.
Nearly simultaneously, another man delivers a swift blow to the second victim's head, at which point the victim collapses to the ground face first.
Byrne and Curran were in New Orleans for the annual general assembly of the Unitarian Universalist Association, said the group's spokeswoman Rachel Walden.
State law defines second-degree robbery as taking "anything of value" from someone and inflicting "serious bodily injury".
Seconds later, one of the robbers runs back into frame and briefly lifts Byrne off the sidewalk by the back of his shirt, revealing what appears to be a large pool of blood, before dropping him back on the sidewalk and running away. The attacker then rummages through the motionless Byrne's pockets as two other robbers arrive on the scene, one of whom pats Curran down.
