Authorities are warning residents in south suburban Dolton of a man who is wanted for two sexual assaults and a robbery in the last week.
"We consider this person to be brazen, very aggressive," said Dolton Police Commander Darryl Hope, who was going door-to-door Wednesday to warn area residents about the crimes.
All the attacks happened in broad daylight, police said, the first on April 30.
"The first female on Woodlawn was sitting in her car talking on the phone when she was approached by subject, who made her roll down the window, open up the door, move over to other side, and then drove her to the location, a vacant property, and sexually assaulted her," Hope said.
Police say the second similar attack happened May 8 on 151st and Dorchester as the woman was walking to work. Before that assault, authorities said the man was captured on surveillance video. He is described as 5'5" to 5'7" tall, and has short twists or short natural hair. Police consider him armed and dangerous.
"He doesn't have any heart or any fear for what he does," said anti-violence community activist Andrew Holmes. "What we're trying to stop is him running up on a female and she refuses or rejects what he wants her to do and then all of sudden that weapon goes off and we have a murder out here."
Police say they believe the same man robbed a man and woman at gunpoint in their driveway on May 8.
There is a $1,000 reward for information leading to the suspect's arrest. Anyone with information on these crimes is asked to contact the police.
