The family of a Sri Lankan woman who died at an immigration facility in Japan is seeking full disclosure of a video showing her near the end of her life.
Wishma Sandamali, aged 33, died in March at the facility in Nagoya, central Japan. She had been detained there for overstaying her visa.
The Immigration Services Agency released a final report in August admitting that the facility lacked a system for providing proper medical care to detainees.
Later, parts of a video showing Wishma at the facility were shown to her sisters, who had traveled to Japan from Sri Lanka. They are now asking to see the full video in the presence of their lawyer.
At a news conference in Tokyo on Tuesday, one of the sisters and the lawyers said they plan to sue for damages from Japan's government.
They also revealed that they were allowed to see parts of the video with their lawyer for the first time last Friday, after the Nagoya District Court approved their request to preserve evidence.
The video clips, taken over two days in late February and five days up to Wishma's death on March 6, reportedly included footage not disclosed by immigration officials.
Footage from March 3 reportedly showed staff trying to force-feed Wishma after she had vomited, without rinsing out her mouth.
Wishma's sister Poornima told reporters that watching the video convinced her that much was missing from the final report.
The family's lawyer Komai Chie said such cruel force-feeding is not mentioned in the final report. She stressed the need to disclose the full video.
