Scammer pretending to collect money for Police Benevolent Association. They just want your credit card number so they can max it out and rob you. Also, they aren't in Denver. That is a a spoofed number. They are overseas.
Ask them for their name and a local cop who could verify they are honest. So told him I needed his badge number of himself or his cop friend , so my nephew could check him out. I don't understand why he hung up on me???
