Relatives of a Sri Lankan woman who died last year while detained at a immigration center in central Japan will file suit for damages against the Japanese government later this week, a source familiar with the matter said Tuesday.

The suit to be brought in the Nagoya District Court, possibly on Friday by the family of Ratnayake Liyanage Wishma Sandamali, 33, will follow a criminal complaint they filed in November against senior officials of the Nagoya Regional Immigration Services Bureau for causing her death due to a lack of medical care.

Wishma, who arrived in Japan in 2017 on a student visa, was taken to the facility in August 2020 after overstaying her visa. She died on March 6 last year while in custody after complaining for more than a month of symptoms including stomach pain.
