The city of East Grand Rapids is warning residents of some strange behavior that's been occurring on a trail near Reeds Lake.

The city took to Facebook Wednesday to tell residents about what had been going on. According to the post, a man who is described as in his 30s, between 5'10" and 6' tall, with dark hair, has been approaching people on Reeds Lake Trail wearing only his underwear. That's weird enough, but it gets weirder.

The post also explains that in all three incidents that have been reported, the man was either dancing or making lewd gestures.

There have been reports that the suspect drives a grey crossover vehicle. The three incidents occurred Thursday, Oct. 18 at 1:14 p.m., Friday, Oct. 19 at 12:40 p.m. and Monday, Oct. 22 at 6:57 p.m.

Thus far, the man has not exposed himself or physically assaulted anyone.

Anyone with information regarding the case is asked to call the East Grand Rapids  Department of Public Safety at 616-949-7010 or Silent Observer at 616-774-2345.

If you encounter this individual, you are urged to call 911 immediately.
