The city of Terrell Hills issued a warning Tuesday morning involving another instance of an alleged robbery perpetrated by someone claiming to work for CPS Energy.
According to the statement issued by the city, around 10:30 a.m. on Monday, an unknown female suspect was seen standing outside the elderly victim's front gate.
"Our elderly resident was approached by a female suspect claiming to work for CPS," said Det. Gail Baham, with the Terrell Hills Police Department.
Baham said the suspect told the victim CPS crews were working on underground phone lines.
The victim said the suspect asked to take some measurements of the backyard and while they were back there, some other unknown suspects robbed the victim's home.
"While they were back there, some unknown suspects entered through the front door," said Baham.
The suspect is described as being an Hispanic woman, about 5 feet, 6 inches tall, with a thin build. She had her hair pulled back and was wearing a baseball cap.
According to the city of Terrell Hills statement, the suspect was not wearing any clothing displaying CPS Energy's logo.
In the past, CPS Energy officials have addressed similar scam claims.
They say that if someone from CPS Energy does knock on your door, they should be wearing CPS logos and have an official ID with an employee number on it.
Customers can ask for that number and call it in to their security office to verify the employee's identity.
The security office is open 24 hours a day, 365 days a year. The number is 210-353-4000.
Terrell Hills officials also reminded citizens they can contact police in such cases.
"Feel free to call us day or night," said Baham. "We will come out and verify their ID."
