Waterloo Regional police have charged a woman with mischief after she allegedly made a false report about a sexual assault.

Police say an investigation into the alleged sex offences began on Feb. 16 after a woman reported that while walking her dog in Kitchener she was assaulted by three males.

An investigation into the circumstances led police to determine that the incident had not occurred and the victim had provided incorrect information.

The 23-year-old Guelph woman has been charged with public mischief.

Police are reminding the public about the drain on valuable resources caused by false reports.
