A would-be taxi driver from the West Midlands who faked a letter from the New York Police Department in a bid to get a licence has been found out.
The driver, from Sandwell, sent the local council a letter claiming to be from the NYPD as evidence of good conduct.
The letter was needed by the authority as the applicant had lived in the UK for less than five years.
However, the taxi licensing office became suspicious and liaised with the NYPD who confirmed the letter was forgery.
It was a great example of multi-agency co-operation, not just locally, but across the Atlantic."
