TOKYO (AP) -- A Japanese coast guard officer is being questioned after he acknowledged having leaked a video of a collision between a patrol vessel and a Chinese fishing boat, a senior official told parliament Wednesday.
Japanese authorities have been trying to determine the source of the leak, which has raised concerns of a new flare-up in tensions as Japanese and Chinese leaders meet at a Pacific rim summit in Japan this weekend.
The video, posted on YouTube last Thursday, shows the Sept. 7 collision near a group of islands in the East China Sea claimed by both Japan and China. The collision and Japan's detention of the fishing boat captain sparked a sharp rift between the countries, with China suspending ministerial-level contacts.
The video has not been officially released, prompting criticism of government secrecy. An edited shorter version was shown to some legislators.
The coast guard officer could face charges related to violating secrecy laws, but could also become a public hero for sharing the video. Coast guard chief Hisayasu Suzuki, responding to questioning by an opposition lawmaker in parliament, said the officer had told his captain that he posted the video on the Internet, but did not give other details, saying the case was still under investigation.
