My fiance just returned home from Nigeria and he has been detained 4 days at Reagan International airport because he returned with electronic sonar hardware he used for his job. Customs has detained him at Reagan International Airport because he only has $2000 of the full $4500 they are requiring. A Diplomatic person tells me he will have to take it back. What do we do?

This Diplomat told me that he has been helping him by allowing my fiance use of his cellphone. I asked Customs Diplomat what if we cannot pay it can he still come into US and come home? He said because it is hardware he will have to take it back. I also asked Customs to give me some sort of documents that shows why such a high amount. He said I would get a receipt with all the info after payment which makes no sense. My fiancee is a US Citizen and his Passport is Valid. I cannot understand this.

He is here in Washington DC at Reagan Airport. I had no idea who to contact and there's a 3 hour time difference

Yes he did go to Nigeria and he wanted to surprise me with an early return.

The phone number is to a man who says he is Mr. Edwards with the Diplomatic Office at Reagan Airport. I'm calling Regan tomorrow to investigate and report this.

Update: I have now talked to my fiance and he is Washington DC.

Update 2: I did call Regan Airport (Thank you Dorothy) Police Command. They told me to contact my local authorities and also to go to Secret Service.gov and file report. He said he thinks they'll be interested since I've recorded all calls, Screenshot all text, Logged all numbers. I also contacted the Bank I was told to Deposit the money into. I have them the Name this "Diplomat" uses and the account and routing numbers plus Name of account holder to verify. I was told nfo did match. They are contacting authorities in their area. She said account holder would be guilty of money laundering and fraud..
