London: A 25-year-old Indian-origin care home worker who sexually assaulted elderly patients, including a 101-year-old woman, has had her jail term increased to 15 years from the previous 10 years.

Christina Sethi targeted three victims, one male and two female, at a care home in Devon, south-west England, between January 2014 and May this year. She also filmed the assaults on her mobile phone before sharing them with her boyfriend.
