A high school student working as an intern at the Central Jakarta municipality office reported three staff members at the office for allegedly sexually assaulting her while she was working in a room at the office, the police said on Friday.

Central Jakarta Police deputy chief Adj. Sr. Comr. Roma Hutajulu said that before the assault on Wednesday, the three men, identified only as H, Y, and Z, smothered the victim until she fell unconscious.

“When she woke up she found herself totally naked. She said the three civil servants sexually assaulted her,” Roma said on Friday as quoted by tribunnews.com.

He said the police had questioned the three men and were holding her high school uniform as evidence.
