LANSING TWP. - Close to a dozen state police officers in tactical gear stormed a house in Lansing Township Friday afternoon after a 14-hour standoff.

And found it empty.

The suspect, who police say attacked his neighbor with a shovel Thursday night, is being sought on a felony assault warrant, Lansing Township Police Chief Adam Kline said.

The suspect's name hasn’t been released, though Kline said he’s a 47-year-old man, 6-feet-2-inches tall and weighing about 200 pounds. He has brown hair and brown eyes and was last seen wearing cut off jean shorts and brown T-shirt, Kline said.

A state police tactical team attempted to get anyone inside to come out using loudspeaker messages and smoke prior to entering through the front door around 12:45 p.m. Friday. They found no people or weapons inside.

Police had the 200 block of Mifflin Avenue cordoned off starting at approximately 10:30 p.m. Thursday. The neighbor who was struck by the shovel was treated by an ambulance crew at the scene and released.

Officers from the state police, Michigan State University police and Lansing police all assisted Lansing Township officers with the incident.

Police negotiators talked to the suspect on the phone as recently as Friday morning before he stopped answering their calls, Kline said.

Anyone with information on the situation is asked to contact police at 485-1700.
