PORT-AU-PRINCE, Haiti — Homeless victims of Haiti's earthquake said Monday that police are halting deliveries of food and water to try to force them to leave their camp on the grounds of the prime minister's office.

Police padlocked the main gate to the hillside camp, where about 2,500 homeless people live under bed sheets and tarps propped on sticks on the sloping hill leading to the office. Stinking garbage with swarms of flies was being allowed to pile up and portable latrines were filled, camp residents complained.

Witnesses said police beat 22-year-old Dalida Jeanty after she picked up a broom to sweep around her tent. "They called her and she did not come so they beat her," said her cousin, Alix Jeanty.

He was among the friends and relatives who carried the woman down the hill, where U.N. peacekeepers from Chile and India arranged for her to be taken to the hospital.

A police officer guarding the gate to the prime minister's office refused to give his name or comment on the alleged beating. Nor would he discuss accusations they have been turning away trucks carrying food and water for the past 10 days.
