Japanese authorities will not be held responsible for the death of a Sri Lankan woman who died while in custody at an immigration center in Nagoya last March, after prosecutors decided to drop the case against the then-senior officials on Friday.

Ratnayake Liyanage Wishma Sandamali¡¯s relatives filed a criminal complaint with the Nagoya District Public Prosecutors Office last November against the immigration center¡¯s senior officials, accusing them of causing her death by failing to provide appropriate medical care.

The prosecutors office had been investigating the case as suspected murder and abandonment by a person responsible for protection, based on Wishma¡¯s medical report, testimonies of the parties involved and insights from medical experts. But they have decided to drop all criminal charges against the then-senior officials on the grounds that they could not be proven.
