A former militant leader has been arrested in connection with the murder of Wall Street Journal reporter Daniel Pearl in Pakistan in 2002.
The leader of the outlawed Sunni militant group Lashkar-e-Jhangvi, Qari Abdul Hai, was arrested yesterday during a security crackdown in Karachi.
Mr Pearl was kidnapped in Karachi while researching a story on Islamist militants in the months after the 11 September 2001 attacks on the US.
Khalid Sheikh Mohammed, the al-Qaeda militant who claimed responsibility for the US attacks, said he beheaded Mr Pearl after his abduction.
It was not clear what role Mr Hai was suspected of playing in the abduction and murder.
The LeJ group has emerged as a major security threat in Pakistan.
It has claimed responsibility for a series of bombings that killed hundreds of Shias this year.
Security officials said Mr Hai has been linked to several attacks on western targets since Mr Pearl's death.
