Thiruvananthapuram, Aug. 12: A young nun killed herself in her room yesterday after leaving an alleged suicide note blaming the mother superior, prompting calls for a probe into “unsavoury” happenings inside convents.

Sister Anupa Mary’s father Pappachan, a cook at Catholic Bishop’s House at Kollam, 70km from the Kerala capital, claimed she had been sexually abused.

He said Mother Superior Albena forced his daughter, 22, to “go into her room to share her bed”.

Congregation Superior-General Boniface Mary welcomed an impartial probe but another nun said the mother superior was a different person, Sister Seeja.

Pappachan said his daughter — found hanging from the fan in her room at St Mary’s Convent, Port Kollam — was driven to the extreme step by the “callous” mother superior.

A nun at the congregation’s headquarters at Kollam said the nun had “never” given them any clue to her “alleged problems”.
