I watched Shark on Star World just now and just learned this new term - Rape in Concert which means that by their (those who involve in the act) presence at the time of the alleged assault, they assisted in facilitating the crime. In other words, they could be one or more person raping the victim and the rest just assist/help to make it happen. It's different from gang rape where everyone in the group joins the 'party'. Phew!!! that's scary.
p/s : I'm supposed to write my high tea reunion with my old school mates but I have problems uploading the pictures...Huhuhu.
