Sangeetha was found hanging in her parent's house last night, hours after she came there to see her ailing father, police said.
The woman, whose husband had gone to Muscat for employment soon after the marriage, was being allegedly harassed by her in-laws for more dowry, police said.
A case has been registered against the in-laws. An inquiry by the Revenue Divisional Officer ordered as required in cases of death of women within seven years of marriage, police added.
