An Antioch, IL, teen has been arrested in connection to the fatal shooting of two people at a Kenosha protest Tuesday night.

Kyle Rittenhouse, 17, was arrested in Antioch on Wednesday, WTMJ reports.

The shooting happened just before midnight Tuesday. Earlier on Wednesday, Kenosha County Sheriff David Beth said authorities were searching for a possible "vigilante" who was seen in several social media videos running through the area with a long gun.

Rittenhouse will be charged with first-degree intentional homicide.
