According to the Sri Lanka Human Rights Centre, the death of the woman, identified as ‘Mali’, was due to her not being given treatment.
She was one of the several female inmates who were badly assaulted after they started a protest on August 13 demanding minimum facilities for them.
The 35-year-old from Wellawatte was in prison over drug charges.
The night before she died on August 24, ‘Mali’ had cried out, asking for medical treatment, which went ignored, although her cell was located next to the prison hospital, where two doctors were on duty at the time, HRCSL executive director Keerthi Tennakoon says.
Male officers assaulted them
During their two day protest on the roof of the prison building, 41 female inmates were brought down, taken to rooms and assaulted by male officers.
They have suffered broken limbs and bleeding head injuries.
However, most of them were not given treatment.
A similar incident occurred at Vavuniya prison in November 2011, where three inmates died of injuries.
The officers who were responsible for that attack and went unpunished, are now serving at Welikada prison, Tennakoon says.
He adds the government should safeguard the rights of prisoners in accordance with the international recognition that prisoners too, are human.
