Indonesian police have arrested two village officials on Borneo island for allegedly beating a pregnant journalist until she suffered severe bleeding and had a miscarriage.

Nurmila Sari Wahyuni, a 23-year-old reporter for Paser TV, a station in East Kalimantan province, was allegedly ambushed by two men on a motorcycle Sunday while she was filming in Rantau Panjang village.

East Kalimantan police chief Maj. Gen. Anas Yusuf said Wednesday that the men recognized Wahyuni as a daughter of one of the owners of disputed village land. He said they beat her and trampled on her legs, stomach and head. She was hospitalized after the attack.

The village chief and secretary were arrested and other people are being questioned.

Sunday's assault sparked outrage among activists and independent journalists' associations.
