SAN LEANDRO -- Suspects posing as city utility workers checking on possible flooding scammed an elderly resident last weekend and burglarized her home, police said.

A woman in her 70s who lives in the 1000 block of Dutton Avenue, just east of the Roosevelt Playground, told police that a man and a woman knocked on her door just before 12:30 p.m. Saturday saying they were there on behalf of the city to investigate flooding, Lt. Randy Brandt said.

The homeowner took the man and woman into her home, where they pretended to check on potential water issues, Brandt said. While inside, the suspects stole items then left the home and got into in a small, dark-colored pickup truck and drove off in an unknown direction.

Police did not release information on what the suspects took from the woman's home, and an estimated value of the stolen items was not known.

Police described the first suspect as being a white man in his 20s, with an average height, medium build and brown hair. He wore a dark sweatshirt. The second suspect was a white woman with blonde hair in her 20s, 5 feet, 5 inches tall with a thin build. She wore a light-colored top.

"Citizens should not allow anyone into their residences without confirming with their utility companies prior," Brandt said Tuesday. "Very rarely will a utility company need to enter a residence to investigate potential issues."
