COLOMBO, Sri Lanka (AP) — A Sri Lankan women’s rights group says the government is arresting innocent female relatives of males it suspects are trying to revive the Tamil Tiger rebel group.

Women’s Action Network on Wednesday described the cases of six women it says were arrested because authorities suspect their male associates or family members have rebel links. The group’s statement said the Criminal Investigation Department has detained some women who are elderly or need medical and psychiatric care but are being denied those facilities.

Police spokesman Ajith Rohana said the women were detained for offenses under the Prevention of Terrorism Act like harboring terrorist suspects.

Sri Lanka’s government claims that the defeated Tamil Tigers are trying to regroup and that it is taking preventive measures.
