LANSING TWP. — Police said they've caught a man suspected of riding up to women on a bicycle and hitting them on the buttocks.

Justin Siebert, 18, of Lansing Township, was arraigned Wednesday in 55th District Court on two counts of fourth-degree criminal sexual conduct, a high-court misdemeanor.

Lansing Township police announced the arrest Wednesday afternoon on Facebook.

Earlier this week, police released photos of a man who two women said rode up behind them on a bike and "smacked them on their rear ends," township police Chief John Joseph said.

The first assault was reported to have happened Wednesday and the second on Saturday. Both took place in the Groesbeck neighborhood, Joseph said.

A similar assault occurred in East Lansing on Friday, Michigan State University said in an alert sent out to the community.

East Lansing police reported that a black man in his early 20s wearing a dark T-shirt had sexually assaulted a woman in the parking lot of Tabooli on Grand River Avenue near Harrison Road. Joseph said the assault was similar to what happened in Lansing Township.

Fourth-degree criminal sexual conduct carries a maximum penalty of two years in prison.

It was unclear if Siebert is represented by a lawyer. His next court hearing is scheduled for Aug. 1.

Township police are asking that anyone who was victimized in a similar way call 911 if they have not already reported the incident.
