The accused told police that he had been raping his 17-year-old sister and also molested his 13-year-old sister from last April, a senior police officer said.
Their father had died. Their mother was bedridden and the brother took advantage of this, he said.
The girls told about the incident to their friend who informed her father, who works with an NGO. They then reported about the incident to police this afternoon, said the officer.
