JAKARTA - AN INDONESIAN woman has been arrested on suspicion of killing and mutilating her husband before dumping his dismembered and headless body on a public bus, police said on Wednesday.

Police said the woman had confessed to the crime but she had not been charged as the body still had not been formally identified.

'Since we still can't find the victim's head, we will need to conduct a DNA test to ascertain his identity first', police spokesman Abubakar Nataprawira said.

Police have not named the suspect but she was identified in The Jakarta Post as 48-year-old Sri Rumiyati, from Central Java.

She had complained to neighbours that her husband beat her and burned her with cigarettes, the daily reported.

Thirteen body parts, including the torso, arms and feet were found stuffed in a bag under a seat on a crosstown Jakarta bus in August. -- AFP
