On December 16, 2010, The CIA evacuated its station chief, later named as Jonathan Bank, from Pakistan after his cover was blown in legal action brought by relatives of a person killed in a 31 December 2009 drone attack, for which the station chief was accused of being responsible.[12] The CIA, in a rare move, recalled the station chief, citing "security concerns" and concerns about his safety.[13] Neither the CIA nor the US government officially recognise station chiefs, but they are acknowledged to exist by intelligence organizations.[14][15] In April 2015, the Islamabad High Court ordered police to open a criminal case against Bank for murder, conspiracy, terrorism and waging war against Pakistan.[16]
