BANDUNG - Two sisters committed suicide by jumping from the fifth floor of the Gateway Apartment in Bandung, West Java, on Monday afternoon.
Based on video footage, which went viral on social media, the two sisters jumped from the apartment after climbing over a balcony rail.
The older sister, aged 34, jumped first. Her 28-year-old sister jumped seconds later.
Several people recorded the incident on their mobile phones.
During police questioning, the two victims' 39-year-old brother said of his two sisters had suffered psychological disorders for eight years.
They were once treated at mental health clinic Penuai Indonesia Foundation, Bogor.
"They had mental health problems since 2006, when their mother passed away," said Bandung Police chief Sr. Comr. Hendro Pandowo, quoting the victims' brother.
