Chicago police say Chaurvet Stiggers also goes by the aliases Rashaun Little, Andre Harris and DeAndre Harris.
The man wanted in connection with at least two sexual assaults and other attempted assaults on the city's Southwest side has turned himself in.
Chicago police said Chauvet Stiggers, who also goes by the aliases Rashaun Little, Andre Harris and DeAndre Harris, surrended himself to police just after 7 p.m. Wednesday. He was with an attorney, police said.
He has not been charged with a crime.
Earlier this week, police issued a community alert after two teenaged girls claimed they'd been sexually assaulted by a man in a green minivan. One of them was at gunpoint.
Another teen said she saw the man expose himself to her. A fourth teen said she was approached but got away.
In all four cases, police said the teens described a black man in his 20s with braids and twists in his hair.
Stiggers is a 23-year-old black male, 5-foot-10 and 150-180 pounds with black hair and brown eyes, according to the alert that went out earlier Wednesday. He wears his hair in braids or twists.
It was believed that Stiggers was driving a green 1996 Chrysler Town & Country minivan with temporary license plates of 265L796, according to the alert, which said he was last seen in the area where the attacks occurred.
