ISLAMABAD    -    PTI leader Senator Azam Khan Swati on Monday approached the Supreme Court and filed a petition over his arrest by the Federal Investigation Authority (FIA) in a case related to “controversial” tweets. The PTI senator was taken into custody by the FIA’s Cybercrime Wing (CCW) from his home in Islamabad on October 13 after registering a case against him over tweets against the army chief. However, he was granted post-arrest bail last week in return for surety bonds worth Rs1 million. In his petition, Swati said that the FIA violated the sanctity of his house. He alleged that he was beaten in front of his family.
