The government is weighing the idea of releasing video footage of Monday's collision between a North Korean fishing vessel and a Fisheries Agency patrol ship in Japan's exclusive economic zone, Chief Cabinet Secretary Yoshihide Suga said Friday.

"We are considering when and how to release it," the top government spokesman said at a news conference. "The video captured the scene when the collision occurred," he said, without elaborating.

The government was reluctant to release the video during the Japan Coast Guard's investigation, but a government official said the same day that releasing it "will no longer affect the investigation."
