First I received call from Police for Police Pledge fund to donate some money,so I told him( I do not Know the Police name)to donate $10 in cash. then he transfered the call to his branch to confirm the donation.A lady ask my name ,last name,& address to pay either  credit card,but I refused to pay by creditcard,then she told me to pay by money order or by check.She will send me the police pledge donation paper, & then Ihave to send donation .But I checked on google about this nphone number & thank God I could Know this is a scheme. I will not send donation.
