A quick-thinking jogger snapped a photo of a flasher in a park at Doncaster East

A quick-thinking jogger has snapped a photo of a man she says exposed himself at Doncaster East last month. 

The woman was running around Ruffey Lake Park on April 18 when she spotted the man sitting on a bench just before 6pm.

As she ran past him, he is alleged to have flashed his genitals at her.

The woman managed to run back past and take a photo of the man, then reported it to police. 

The man never threatened her or followed her, he stayed seated on the bench after she left.

Police have released the photo taken by the woman.
