RENO, Nev. (AP) - Police say a gunman is holed up at a Walmart in Reno after he allegedly shot three employees who have been hospitalized with non-life threatening injuries.

Reno Deputy Police Chief Mike Whan (WHAHN) says the lone gunman entered the store about 8:30 a.m. and started shooting in the direction of an employee or employees.

He says the three injured employees are being treated at a hospital.

About 100 people in the store were safely evacuated.

Police believe the gunman is in a back room. Whan says they are trying to contact him, but there's been no dialogue so far.
