ISLAMABAD- Three British men of Pakistani origin have been sent back to Britain, where they are wanted for questioning in connection with the murder of a teenaged boy in 2004, the British High Commission said on Thursday, according to Reuters.

The three, who a Pakistani security official said were from the Scottish city of Glasgow, were arrested in Pakistan three months ago.

The men were sent back to Britain on a flight on Wednesday. They have been wanted in connection with the murder of schoolboy Kriss Donald in March 2004, the High Commission said.

&#34The murder of Kriss Donald was a vicious crime against an innocent 15-year-old boy that caused revulsion throughout the UK,&#34 High Commissioner Mark Lyall Grant said in a statement.

&#34The search for justice in this case continues, but I”m pleased to be able to say … that we have moved that process on considerably with the return of three suspects.&#34

The High Commission did not identify the three.

Britain and Pakistan do not have an extradition treaty but, following lengthy negotiations, Pakistani authorities amended a

1972 extradition act to allow for the return of the three, Lyall Grant said.
