The Sunnyside Police Department has in the past few weeks been alerted to counterfeit $100 bills circulating in the city.
"We have confiscated approximately 10 of them," said Officer Melissa Rodriguez.
She said the counterfeit bills are of high quality and a marker commonly used for detecting counterfeits is not sufficient.
"The money is real...it appears they (the counterfeiters) have washed $5 bills and re-printed them with $100 values," said Rodriguez.
She said the police department is wary there may be $20 and $50 bills also circulating, although they have not yet been alerted to any.
"Look very closely at the $100, $50 and $20 bills you receive," said Rodriguez, advising the community to be on the lookout for the counterfeit money.
She said the police department urges anyone who believes they may have discovered a counterfeit bill or who wishes to receive more information about the counterfeit money being circulated to call 836-6200.
Sunnyside police have taken into custody one suspect, Senaiva Ann Gonzalez, 37, of Sunnyside. Requested charges are pending and the investigation is ongoing.
