According to police, the two men work together to distract the residents.
This is how they operate. One man knocks on the door and tells the resident there was a broken street pipe and that they should check the tap water.
While the resident is distracted, the second man tries to burglarize the home.
Officials say there have been two such instances in April.
If you any have information about the suspect, you're urged to call the West Covina Police Department at (626) 939-8688.
