Police in the southern Indian state of Kerala have arrested a woman in connection with the suicide of a man she had accused of touching her inappropriately on a bus.

The arrest followed a complaint by the man's family, who alleged that he faced online harassment after a social media video posted by the woman went viral.

Shimjitha Musthafa, 35, last week posted the video she recorded on the bus, offering it as evidence against Deepak U, 42, whom she accused of elbowing her on the breast.

In a country where sexual harassment of women in crowded public spaces is rampant, the footage sparked strong reactions, with many criticising Deepak. Two days later, he died by suicide.

Deepak's friends and family say he had denied the accusations of sexual harassment and that he was innocent. They also said he was distressed by what they described as a "social media trial".
