A human rights activist says Sri Lanka's police arrested a woman and her 13-year-old daughter in what the activists say is part of the government's continuing efforts to intimidate families of the country's civil war-missing into silence.

Balendran Jeyakumari and her daughter Vithushaini were arrested in the northern Kilinochchi district Thursday night after military and police held them house-bound for hours, the activist said on condition of anonymity fearing military reprisals.

Jeyakumari had been vocal in calling for the release of her 15-year-old son, a child recruit of the Tamil Tiger rebels whom she had handed to the military as fighting ended in 2009.

Police spokesman Ajith Rohana says Jeyakumari was arrested for harboring a criminal.
