Two California women allegedly posed as Internal Revenue Service employees in a nationwide phone scam that may have bilked several victims out of nearly a million dollars, police said.

One of the victims received a “cold call” Sept. 4 from someone posing as an IRS agent who threatened to arrest him if he didn’t pay $2,200 in Target gift cards, The Fontana Police Department said Friday.

The victim complied with the caller’s instructions and later alerted the cops.

Investigators traced the gift cards to a Target in the Los Angeles area and used surveillance footage to identify two suspects, Ailing Lu, of Los Angeles, and Ji Hyun Lee, of Gardena, both 25.

Detectives found about $900,000 worth of new electronics, gift cards and other items at two locations and in vehicles linked to the women.
