Police remain on the scene searching for a gunman after shots were reported fired at a North Side building on Sunday afternoon.

Officers responded to a call of shots fired at the building in the 2700 block of North Pine Grove Avenue in the city’s Park West neighborhood about 3 p.m., according to Officer Kevin Quad, a Chicago police spokesman.

“Out of an abundance of caution, SWAT was called,’’ but no victims or suspects could be found.

As of 4 p.m., officers remain on the scene searching the area, including the roof of the building, Quaid said.

According to preliminary information from police, the suspect may have been a man with white hair or wearing a white hat who might have been shooting from the roof of the building. A bullet casing was found, police said.

No suspect was found, said police who were looking at surveillance video from the area.
