London: The 32-year-old sister of an Indian-origin Islamic State suspect was on Wednesday given a restraining order preventing her from any contact with a UK journalist after a court was told that she had become "obsessed" with him following an interview.

Konika Dhar, the sister of British Muslim convert Siddhartha Dhar who was dubbed "Jihadi Sid" by the UK media after featuring in ISIS videos, was said to have bombarded Sunday Times security correspondent Richard Kerbaj and his ex-girlfriend with inappropriate messages after he interviewed her for a documentary about relatives of ISIS terrorists in 2015.
