While the Indian Mujahideen used weak wi-fi (wireless fidelity) security in Navi Mumbai to send terror threats over email, a Khar resident recently did the same to terrorise his estranged wife, according to a report in the DNA.

According to the police, Pavan Muthreja, 25, used the wi-fi network of a woman staying in a neighbouring building to send obscene and threatening messages to his estranged wife, aged 22. He even posted scraps making dowry demands. Muthreja's wife had walked out a month into their marriage in September 2008, alleging harassment.
