The NYPD never solicits charitable donations.

The NYPD states that New Yorkers have been conned out of millions of dollars by telemarketers who falsely claim to be soliciting donations on behalf of the NY Police Department.
They imply that their donations will be used to support the NYPD, or help widows and children of slain officers.
They may even offer a police decal or similar item implying special police treatment.
If you receive such a call, take down as much information as possible, ask for written information and then report them to:

NYPD Internal Affairs Bureau   212-741-8401    You don’t have to give your name.
