The man told the woman who answered the door that he was working on a sewer line and needed to access her backyard to check on something, police said.

Although the woman initially allowed him into the yard, she reconsidered and asked him to produce a badge or other form of identification.

The man, when confronted, said he was going to retrieve identification from his vehicle. Instead, he sped off in what police said was a dark red or burgundy van.
