A biker was indicted Thursday night in connection with the well-publicized clash with a New York SUV driver, according to the Manhattan District Attorney's office.
Officials did not release what charges Robert Sims was indicted on. Sims was accused of stomping on SUV driver Alexian Lien and faced assault charges.
Sims is one of seven people who face charges in the melee.
Authorities, who have appealed for the public's help in identifying people in photos, haven't ruled out more arrests or charges.
The incident was sure to get attention, taking place on one of the busiest roads in one of America's busiest cities.
But the story caught on even more after video of the episode went viral.
According to Assistant District Attorney Samantha Turino, motorcyclists heading north on Manhattan's West Side Highway "were driving recklessly, ... obstructing vehicle traffic, running red lights, swerving between lanes" when one of them, later identified as Christopher Cruz, quickly slowed down in front of Lien, the SUV driver.
Lien's vehicle bumped Cruz's rear tire, slightly injuring him.
The Range Rover then pulled to a stop, at which point angry bikers surrounded his vehicle, hit it and spiked its tires, police said.
Lien's vehicle then began moving again, plowing into three more bikers, including Edwin Mieses, critically injuring him. Dayana Mieses said earlier this week she has been told there's only a 1 percent chance her husband will walk again.
As it moved away, the SUV was chased by motorcyclists, who caught up with it near the George Washington Bridge. Several bikers dismounted and approached the vehicle, with one of them opening its door, before Lien then drove away again.
Motorcyclists continued their pursuit, with some speeding ahead of him to help halt traffic. That's where the ordeal ended, with Lien getting dragged out, kicked and hit.
He suffered cuts to each eye, his right cheek, the left side of his body, and his lip, in addition to a pair of black eyes and abrasions to his hand, back and shoulder, according to Turino.
His wife and 2-year-old daughter were unharmed.
