Arumugam, father of three daughters, had married off his two daughters and was living with wife, a 10 year-old son and a 15-year old daughter.
He used to sexually abuse her for the last few years when his wife leaves home for working in a paper recycling unit.
Childline officials said the girl did not realise what she was being subjected to when she was young. However, when she grew up, the gril realised that her father was misbehaving with her and she took up the issue with her mother.
The girl then went to the family of one of her friends two days back and informed about the misbehaviour. They in turn informed her school teachers, who gave a complaint to childline officials, police said.
The officials lodged a formal complaint to the all women police station.
As the parents of the girl did not turn up, the officials took her to a home run by the Child Welfare Committee and police arrested Aramugam late last night and remanded to judicial custody.
