Lansing police have surrounded a house near the corner of Stillwell Avenue and Sumpter Street on the city's southwest side.
A person renting a home on the 4400 block of Stillwell came home to find a door kicked in and a man with a gun standing inside. The renter left and called the police.
A Lansing police spokesman says officers were on the scene within five minutes but they do not know if the armed man is still inside.
Officers set up a perimeter and are telling anyone inside to come out. A police tactical team has been called to the scene.
