QUETTA, PAKISTAN: Pakistan authorities have arrested a journalist under a new electronic crime law aimed at combating terrorism and preventing blasphemy but which critics say is used to suppress political dissent. The journalist, Zafarullah Achakzai a reporter for the Daily Qudrat newspaper, in Quetta city was produced before a magistrate on Wednesday and remanded in police custody under the cyber law, an official from the police's Federal Investigation Agency (FIA) said. He is one of the first reporters to be charged under the electronic crime law, which was introduced in August to the objections of media freedom and human rights activists. Achakzai's father, Naimatullah Achakzai, said his son was detained on Sunday by officers from the Frontier Corps, a paramilitary force in overall charge of security in Baluchistan province, of which Quetta is the capital. 'Some 50 people came to our home at 6 am and kicked down the door,' Achakzai said, adding that police filed a case against his son under the cyber crime law on Wednesday. Police had shown him the filing, he said. 'We weren't allowed to talk to him or meet him,' he said, adding he believed is son was arrested over social media posts. The elder Achakzai said he believed his son was in trouble because his social media activity. The son posted a comment on Facebook after a suicide bombing killed 13 in Quetta this month, in which he questioned why the Frontier Corps had responsibility for policing the city. Reuters was unable to reach officials at the Frontier Corps for comment. The FIA official, who declined to be identified, confirmed that the journalist had been arrested by the Frontier Corps, and then handed over to the FIA on Wednesday. The Pakistani media watchdog Freedom Network said it was concerned about what it saw as 'the authorities' zero-tolerance for critics on social media'. 'The arrest of journalist Zafarullah Achakzai is a grim reminder that more arrests will follow for the same reason in the near future,' the group said. Authorities began cracking down on social media in May, with security officials saying that more than 200 accounts were under investigation.
