The Santa Clara County Sheriff's office says someone is claiming to be a deputy and he's trying to scam people out of money.
It's already happened to at least a dozen people in the South Bay.
Rosemary Ferreira of Sunnyvale got a phone call from someone who said he was with the sheriff's office. He told her she would be arrested for not responding to a grand jury summons – unless she paid at least $700.
The man even gave Ferreira what he claimed was his badge number and a warrant number.
Ferreira was skeptical, so she had her husband call the sheriff's department.
“They told me they’d had at least 11 people who had received that same phone call,” husband Boyd Smith said.
The sheriff’s department confirms there have been several different scams during the year involving people claiming to be sheriff’s deputies, but would not elaborate on the call Rosemary received.
Rosemary says she’s glad she didn’t fall for the scam and is sounding the alarm so others who get a similar call won't either.
