Police sent to free aid workers

Apolice unit was sent to obtain the release of an American relief worker being held captive in southern Cambodia by Khmer Rouge guerrillas, AP reports from Phnom Penh. Melissa Himes, 24, a former student at Aberdeen University, and three Cambodian colleagues have been detained since Thursday in a village in Kampot province, where she went to try to settle a dispute over the drilling of water wells. Ms Himes said in a note: 'We are OK. As far as I understand, they want three wells. They are being kind to us in providing food and water. Tell my parents not to worry.'
