Hong Kong’s Civil Aviation Department has called the police over leaked information relating to its trouble-plagued new air traffic control system. The call follows the publication this week of an additional image of a radar screen showing flight information. On Wednesday, the department said it was seeking assistance from police over “the recent leak and the suspected improper use of computers”. On November 28, the department issued to its air traffic controllers a warning of disciplinary action for leaking restricted and confidential information.
