WILLIAMSON COUNTY, Texas -- The Williamson County Sheriff's Office is investigating a person posing as Sheriff James Wilson.
Detectives say the suspect is calling people saying they are past due on private accounts, and if they don't make a payment immediately, they will be arrested.
In one case the person actually received an email with a fake arrest warrant supposedly signed by the justice of the peace.
"Law enforcement is not going to call people and request money. Any time people get a call like that, they should not send any money," said Fred Thomas with the sheriff's office.
The call shows up as "The Williamson County Sheriff's Office" on caller ID, but it's actually coming from a temporary cell phone.
If you get one of those calls, contact your police department or the sheriff's office directly.
