Chesterfield Township police said Friday they are continuing to seek tips about a suspected armed robber who struck last month.

Detective Sgt. Deron Myers said they are asking the public to help identify the man who robbed a couple at gunpoint in the 23 Mile and Gratiot area.

The incident stems from around 1 a.m. Nov. 7, when a man in his 20s who spent time in Buffalo Wild Wings approached a couple near the restaurant entrance and asked them for a ride to Meijer. He said his friends were going to pick him up at the nearby store, according to township police.

The couple said once the man was in their backseat, he pulled out a black handgun and demanded their belongings. The pair gave him their cell phones and cash and the robber ran toward Gratiot, where they believe he headed toward a bus stop, Myers said.

Police released a surveillance image in late November from Buffalo Wild Wings of the suspect. He is described as 5'8 to 5'9 with a slim build, beard and mustache. He wore a knit skull cap, dark clothing and tan work boots.

They are asking anyone with information to call Chesterfield Police Department at 586-949-2322 or Crime Stoppers at 1-800-SPEAK-UP.
