Detectives say the suspect exposed himself to girls in a series of three incidents on Jan. 17, Feb. 14 and March 4 between 1 and 5 p.m. Authorities say the suspect may have tried to strike again on Tuesday.
At about 1 p.m., police say a man approached a 12-year-old girl as she walked home from school near the Paseo Westpark and Hearthstone areas.
The suspect reportedly asked the girl for directions.
"When he approached her, he asked her for directions to a community pool," said Irvine Police Lt. Julia Engen. "She knew not to talk to him, because she didn't know who he was so she ignored him and continued to walk."
Police say he followed her to her house, but she was able to get inside safely.
He didn't expose himself, but detectives say he matched the description of the man wanted for the previous indecent exposure incidents.
The suspect is described as a light-skinned man between 20 and 30 years old with short, dark brown hair. His car is described as a black or dark sedan with tinted windows and a partial license plate of 6NHB--- or 6HNB---.
Police say the suspect travels alongside the sidewalk to get the children's attention.
"He asks them a question, and when they look up to answer is when he has been exposing himself," said Engen.
So far, the man has not physically touched the victims, but police are concerned he'll become more brazen. Officials urge students to call for help right away if something happens.
"Even somebody who approaches you, and when you've ignored them, they continue to try to talk to you, that's enough to make a 911 call," said Engen. "We always rather come when we're not needed."
If you recognize him, you're asked to call Irvine Police Department at (949) 724-7200.
