FARMINGTON HILLS, Mich. -

The Oakland County Sheriff's Department is warning residents to beware of callers posing as IRS and law enforcement officials demanding money.

According to Sheriff Michael Bouchard, the Farmington Hills Police Department received a complaint from a resident claiming he took a call from someone posing as an IRS official.

Bouchard said the resident was told he would be charged with a crime if he didn't use a Green Dot prepaid money card to pay the IRS more than $3,800.

The resident paid the amount and then got another call from someone claiming to be Sheriff Bouchard. During this call, the resident was told he owed another $4,500.

This time the resident became suspicious and reported the call to the Farmington Hills Police Department.

Bouchard reminds residents the Sheriff's Department would never make such demands over the phone for any reason.

Bouchard says anyone demanding money in the form of a Green Dot money card should be suspect of trying to pull a scam.

Consumers Energy also is warning people to be aware of scam calls demanding quick payment of utility bills using Green Dot prepaid money cards.

In a news release, Consumers says since Nov. 22 they have received 118 complaints of callers who have falsely claimed to represent the company, demanding payment using the Green Dot card.
