If a person claiming to be a city or utility worker comes to your door, DO NOT LET THEM IN!
They will claim to be performing repairs in your alley and need to come inside to talk to you. IT IS A HOAX! They are actually casing your home to see what they could steal (your valuables and your money).
If they are a legitimate city or utility worker,
1) they will be in uniform with the city's or company's logo on it
2) they will have a city or company identification badge with their picture on it
3) they will have a city or utility vehicle with a logo on it parked outside your home or in your alley. They will never be in an unmarked vehicle.
And,
4) if you yourself didn't specifically call for a repair, don't let anyone claiming to be a city or utility worker into your home
Three senior citizens (2 in Robertsdale and 1 in East Chicago) have had this scam pulled on them. Two were lucky; they were not hurt or robbed. The third was robbed of $500. Thankfully, she was not hurt.
If someone claiming to be a city or utility worker comes to your door and you don't recognize them, err on the side of caution and call 9-1-1. Do not under any circumstances let them in. The police would much rather have a false alarm than deal with an assault and robbery.
And most important, keep your doors locked at all times!
It is much better to be safe than sorry!
