PORTAGE -- Portage Police are still investigating a police impersonation. They've now released a sketch of the suspect. The most recent sighting was last Thursday on Currier Drive in Portage when a suspect, described as a black female in her forties around 5'3" in height with a thin build dressed in all black flashed a gold badge at an elderly woman. She then got in the woman's car and said she had to investigate the woman's home. The driver refused and the suspect fled.
