Video shows a robber disguised as a maintenance worker trying to break into a home only to be met by a full clip from the other side of the door. Everything started when a robber rang the homeowner's door and introduced himself as a maintenance guy. >> Can I help you? >> Oh yes. Uh they came to check your air filters. >> Oh, nobody's home right now. You'll have to wait till another day. Oh, much appreciated. >> Nobody is home. Gave them the green light. Heat. Heat.
