ISLAMABAD, July 5: The Lahore High Court, Rawalpindi circuit bench, has summoned the interior secretary to explain reasons for the arrest of a nuclear scientist.

Attiqur Rehman, the nuclear scientist working with the Pakistan Atomic Energy Commission, was picked up from his Abbottabad home about two years back. His whereabouts are not known.

Mr Rehman’s father, Siddiqur Rehman, filed a writ petition in the high court against the arrest.

Mr Siddiq said that his son, arrested on the day of his marriage, had neither been produced before a court of law nor did his family know where he had been kept.

The court had asked the interior secretary to submit a written reply, but so far no response came from the home department.

On Wednesday, Justice Sardar Muhammad Aslam issued notice to the interior secretary to appear before the court on July 7.
