These are the faces of the ten most dangerous foreign criminals hiding in Britain. Suspected of crimes including murder, rape and torture in their own country, the ten are fugitives from Eastern Europe and America.
Among them are two brothers Wojciech, 28, and Dariusz Glowacki, aged 32, suspected of carrying out a horrific sex attack in Poland on a young girl under the age of 18 who was savagely beaten before her attackers took turns to rape her in January 2002.
The brothers, who have been linked to Slough and Acton in West London, are also wanted over two sex attacks in the same region of Zelechow in the Mazowieckie province of Poland, which took place in September 2000 and December 2001.
Police also want to trace Romanian Neculai Margineau, 49, who is alleged to have punched and kicked a farmer to death after he was caught stealing livestock from a farm in Serbesti in the industrial region of Bacau in Romania in May 1998.
The murder suspect is thought to have connections to Mitcham, Surrey and Enfield, North London.
A Lithuanian gangster wanted in his own country for kidnap, robbery, torture and extortion is also on the list.
Gintautas Rupslaukis, aged 36, is accused of ambushing a taxi and kidnapping two men, torturing them for three days before his captives agreed to sign debt receipts.
After the kidnapping in April 2003 near Kaunas City, Lithuania, Rupslaukis is thought to have gone on the run and he has been associated with the Manchester area.
The gallery of rogues also includes a Briton wanted in the United States for stealing £55,000 of computer and TV equipment from a university.
John McLean, 23, who has previously been linked to Tower Hamlets, in East London and High Wycombe, is being sought over a burglary in February 2006 at George Mason University in Fairfax, Virginia.
The manhunt, codenamed Operation Sunfire, has so far been unable to identify where the criminals are hiding but all are believed to have links to the London area.
The public are being urged not to approach the men who are considered highly dangerous and may be armed.
It is not known if the villains have carried out any further attacks whilst living in Britain.
European warrants for their arrest were issued between Summer 2008 and August this year, although police believe some of them had been in this country for a considerable period of time before that.
The Metropolitan Police received a total of 451 requests for extradition between April and November this year from European countries.
Of those, 291 have been arrested so far.
Detective Sergeant Dean Coyle, in charge of the operation by the Met Extradition Unit, said these 10 were the most dangerous.
He said: 'We are hoping the public's vigilance can help us in tracing these men.
'Many are considered dangerous and should not be approached, however if you spot them or believe you know where they are living, working or frequenting then I would urge you to give Crimestoppers a call so that my team can find and arrest them.
'The countries where these crimes happened want these men back to face justice for these offences and it is in the interests of London to help find them.'
Below are pictures and profiles of the dangerous men, detailing who they are, what crimes they are accused of committing and where they are believed to be hiding.
Anyone with information about any of the men is asked to contact Crimestoppers on 0800 555 111.
