Until it was shut down this summer, the sham embassy was housed in a run-down, pink two-storey building with a corrugated iron roof and flew a U.S. flag outside. Inside hung a portrait of President Barack Obama.

“It was not operated by the United States government, but by figures from both Ghanaian and Turkish organised crime rings and a Ghanaian attorney practising immigration and criminal law,” the State Department said in a statement released late on Friday.

Turkish citizens, who spoke English and Dutch, posed as consular officers and staffed the operation. Investigations also uncovered a fake Dutch embassy, the State Department said.

Officials in the Netherlands were not immediately reachable for comment yesterday.

The crime ring issued fraudulently obtained but legitimate U.S. visas and false identification documents, including birth certificates at a cost of $6,000 each, the statement said.

During raids that led to a number of arrests, authorities also seized authentic and counterfeit Indian, South African and Schengen Zone visas and 150 passports from 10 different countries along with a laptop and smart phones.

The statement did not say how the gang obtained the authentic visas. And the State Department did not say how many people were believed to have illegally entered the United States and other countries using visas issued by the crime ring, which used bribery to operate unhindered.

“The criminals running the operation were able to pay off corrupt officials to look the other way, as well as obtain legitimate blank documents to be doctored,” the statement said.

There was no immediate comment from Ghana’s Criminal Investigations Division.

Visas for Western countries are in high demand in Africa and embassies say the visa market is a big target for organised crime.

The real U.S. embassy in Ghana is a prominent and heavily fortified complex in Cantonments, one of the capital’s most expensive neighborhoods. Lines of people queue outside each day for visa appointments and other consular businesses.
