How did you go about doing the application? I did this recently. Since I have a TRN (TaxPayer Registration Number) I was able to pay the fee at a tax office.
In your friend's case:
Persons living overseas must submit:
1. Finger prints (to be signed and stamped by the police or a reputable agency – the name of the person taking the fingerprints must be clearly stated on the document)
2. Two passport-sized photographs (should not be certified or embossed)
3. Front bio-data page of passport (must be certified)
4. Bank draft/money order made payable to The Commissioner of Police
If the applicant does not have a Taxpayer Registration Number (TRN), payment must be made at the Jamaica Constabulary Force Finance Branch, Ground Floor, NCB North Tower, 2 Oxford Road, Kingston 5, then the receipt and documents taken to the Technical Services Division (Criminal Records Office), 34 Duke Street, Kingston.

I hope that helps.
