REYKJAVIK (Reuters) - An Icelandic court sentenced four former Kaupthing bankers to jail on Thursday for market abuses related to a large stake taken in the bank by a Qatari sheikh just before it went under in late 2008. 
  
 Weeks before the country's top three banks collapsed under huge debts as the global credit crunch struck, Kaupthing announced that Sheikh Mohammed Bin Khalifa Bin Hamad al Thani had bought 5 percent of its shares in a confidence-boosting move. 
  
 A parliamentary commission later said the shares had been bought with a loan from Kaupthing itself. 
  
 On Thursday, a Reykjavik district court sentenced Hreidar Mar Sigurdsson, Kaupthing's former CEO, to five and a half years in prison while former chairman Sigurdur Einarsson received a five-year sentence. 
  
 Magnus Gudmundsson, former CEO of Kaupthing Luxembourg, was given a three-year sentence AND Olafur Olafsson - the bank's second largest shareholder at the time - got three and a half years. 
  
 In what is by far the largest case brought by Iceland's special prosecutor against former employees of Iceland's failed banks, it was argued that the market had been deceived by information indicating that financing was coming directly from al Thani's own funds. 
  
 Special Prosecutur Olafur Thor Hauksson, who called some 50 witnesses in the case, said the loans granted by the bank had the sole purpose of boosting Kaupthing shares. 
  
 None of the bankers, now based in London and Luxembourg, were present on Thursday. 
  
 The estate of Kaupthing said earlier this year it had settled a dispute with al Thani but provided no details, saying only that it had discontinued legal proceedings.

 Four former bosses from the Icelandic bank Kaupthing have been sentenced to between three and five years in prison. 
  
 They are the former chief executive, the chairman of the board, one of the majority owners and the chief executive of the Luxembourg branch. 
  
 They were accused of hiding the fact that a Qatari investor bought a stake in the firm with money lent - illegally - by the bank itself. 
  
 Kaupthing collapsed in 2008 under the weight of huge debts. 
  
 For years, Kaupthing and other Icelandic banks had aggressively pursued overseas expansion plans, but when they went into administration, they brought the country's economy to its knees. 
  
 Just a few weeks before the collapse, Kaupthing announced that Sheikh Mohammed Bin Khalifa Bin Hamad al-Thani had bought a 5.1% stake during the financial crisis in 2008. 
  
 The move was seen as a confidence boost for the bank. 
  
 Legal costs 
  
 Hreidar Mar Sigurdsson, the former chief executive, received five and a half years, while Sigurdur Einarsson, former chairman of the board, was sentenced to five years in jail. 
  
 These are the heaviest sentences for financial fraud in Iceland's history. 
  
 The court gave Olafur Olafsson, one of the majority owners three years and Magnus Gudmundsson the former chief executive of the Luxembourg branch, three and a half years. 
  
 None of them were in court for the decision but it is expected that they will appeal. 
  
 The four were also made to pay their own legal costs for the case, which amount to millions of pounds. 
  
 The special prosecutor, Olafur Hauksson, said the deal had influenced the bank's share price. He also said the loans provided for the deal were illegal. 
  
 Mr Hauksson told the BBC that there was still another, bigger case against Kaupthing Bank ongoing, in which it is accused of market manipulation. It is due to come to court at the end of January. 
  
 Deceived 
  
 Kaupthing Singer and Friedlander was the UK arm of Kaupthing Bank - the largest of the Icelandic banks that went into administration in October 2008. 
  
 According to the Icelandic media, the charges state that the deal was done by first depositing a loan from Kaupthing bank into shell companies in the British Virgin Islands. 
  
 The money then went from there to a Cypriot based company called Choice, which was owned by Olafsson, Sheikh al-Thani and al-Thani's adviser. 
  
 From there it was moved to another firm called Q Iceland Finance, also owned by al-Thani, and then finally ended up back in the bank to pay for the shares. 
  
 It was never publicly stated that the company owned by Olafsson was party to the deal. 
  
 Sheikh al-Thani did not testify but he gave a statement to the prosecutors. In it, he said he did not know of any direct involvement by Olafsson to the deal. 
  
 Al-Thani's lawyers, who made an agreement with Kaupthing's administrators, said he considered himself to have been deceived. |||||
Output:
Iceland has done something highly unusual with some of the bank chiefs blamed for the country's 2008 financial collapse: put them on trial and sent them to prison. Four former Kaupthing Bank bosses have been sentenced to between three and five years for market abuses relating to a deal where a Qatari sheikh bought a confidence-boosting stake in the bank with money that had been provided by the bank itself, the BBC reports. Prosecutors said the loans, made soon before Kaupthing collapsed under massive debts, were made solely to boost the bank's share price, reports Reuters. The bank's former chief executive and chairman of the board received prison terms, along with one of its majority owners and the chief of its Luxembourg branch. The sentences are the heaviest Iceland has ever handed down for financial fraud, but prosecutors say a bigger case against Kaupthing is in the works.
