Islamabad, Nov.7 A former prisoner, who was kept behind bars at the US detention facility at Guantanamo Bay for six years, has vowed to lodge a criminal case against former Pakistan President General Pervez Musharraf for arresting him illegally.

Sami El-Haj, who is a journalist by profession and works for leading Arab television channel Al-Jazeera, said he is "gathering evidence against Musharraf and will file a case against him in a British court".

"I want him [Musharraf] to be in jail," The Daily Times quoted Haj, as saying.

Haj, who belongs to Sudan, alleged that he was subjected to enormous torture by the US officials during his days in detention.

"I had valid travel documents when I was arrested in Pakistan. I hold Musharraf responsible for my arrest and wait for the day when he is tried for this crime," he said.

Haj was arrested from Pakistan's Chaman area on the border with Iran in December 2001.

He also claimed that Musharraf, in his book, had himself admitted that he had 'sold people to the US to earn money'. (ANI)
