Police are looking for half-naked, balding man who was reportedly masturbating and calling out to two young girls as they walked to school Wednesday morning.
The 9 a.m. incident took place near the train tracks in the McIntosh Drive area.
The two girls saw an adult in the area and ran for help.
"The girls did the right thing by finding an adult and asking for their help," RCMP Const. Tracy Wolbeck said in a news release.
"Any cases of this nature are an obvious concern to us," she said, especially because it involves children.
The suspect, described as a large, balding white man with a "slight" beard, was wearing a dark-blue hooded sweatshirt at the time with the word "NAVY" printed in yellow letters.
Anyone with information is asked to call the Chilliwack RCMP at 604-792-4611 or Crime Stoppers at 1-800-222-8477 (TIPS).
