A list of the 20 most-wanted alleged tax-dodgers - who are accused of fleeing the UK while owing the government millions of pounds - has been released.
Names and pictures of the accused have been published for the first time by Her Majesty's Revenue and Customs (HMRC) in a bid to find them.
The list includes Hussain Chohan, 44, who was convicted for his role in a £200 million fraud, part of which involved importing 2.25 tonnes of tobacco worth £750,000 in duty.
He is currently believed to be in Dubai and was given 11 years for smuggling and fraud offences and failing to appear in court - he is also subject to a £33 million confiscation order.
Wayne Joseph Hardy, 49, was convicted for manufacturing tobacco products and not paying duty and was given a three-year sentence in October 2011 - he is believed to be in South Africa. The estimated cost to the taxpayer was £1.9 million.
Nasser Ahmed, 40, believed to be in Pakistan or Dubai, was sentenced to six years in 2005 for his part in VAT fraud worth around £156 million. He fled before verdicts were given and was convicted and sentenced in his absence.
These three men are among 20 people whose pictures and details are on HMRC's Flickr page.
Exchequer Secretary David Gauke said:
These criminals have collectively cost the taxpayer over £765 million and HMRC will pursue them relentlessly.
We hope that publishing their pictures in this way will enable members of the public to contribute to the effort to catch them.
