Two soldiers were taken into custody a week later by police. Two others at the STF camp in Vellaveli have also been arrested.
Local people are concerned and say several incidents of rape remain unreported.
Five soldiers are already in custody for the gang rape of a woman in Kalkudah in November. The Army advanced west towards the Chenkalady-Badalla road with air cover and shelling. Sixteen houses were destroyed by bombs and people say they fled before the Army entered their villages. The military say Tiger vehicles were captured at Ilupadichchenai and a senior LTTE intelligence officer MGR was killed in Kitul. As the Army retaliates after Tiger attacks, civilians are increasingly being affected.
