Law enforcement officials are asking for any information about a home invasion robbery in which four handguns were taken.
Shortly before noon on Tuesday, a man knocked on the back door of a Bethesda, Md., home, Montgomery County police said. When a housekeeper answered the door, he allegedly pushed her aside and locked her in the basement.
The guns were the only items stolen.
Two elderly men who were in the home at the time were not injured.
The suspect is still at large. Anyone with information about the incident is asked to call police at 240-773-5100.
