On Oct. 2, the anti-corruption court, which is trying Sharif's family in four different corruption cases, had issued non-bailable arrest warrants for his two sons and son-in-law, and bailable warrants for his daughter Maryam for deliberately avoiding the court proceedings.

Hussain and Hassan left for London to be with their mother, Kulsoom, who is battling throat cancer.

Former Prime Minister Nawaz Sharif Daughter Maryam Nawaz has said that those who have presented themselves for accountability are being taken into custody while no action is taken against absconding law breakers.
The court rejected NAB's request to confiscate Mr Safdar's passport and to issue his judicial remand, however, the accused has been directed not to leave the country without court's permission.
Maryam Nawaz, before leaving for Islamabad, said the cases against the family were not for justice but for revenge. Maryam was with him but she was not arrested.
The Supreme Court deposed Sharif in July following an investigation into corruption allegations against him and his family, making him the 15th prime minister in Pakistan's 70-year history to be ousted before completing a full term.
Later both Maryam Nawaz and Captain (retd) Muhammad Safdar appeared the Accountability Court Judge Muhammad Bashir amid tight security arrangements. Referring to Pakistan Tehreek-e-Insaf chief Imran Khan who has refused to appear in several cases, Maryam said that the "absconders are free and hold public meetings".
Television footage showed some supporters from the ruling Pakistan Muslim League-Nawaz (PML-N) trying to stop the auto from leaving the airport, including some who lay down in front of it.
She said judges will have to be answerable.
