Police are searching for a group of armed robbers who attacked at least two couples, forcing the men to watch as the women were gang raped.
The two attacks happened two hours apart on Thursday night. In each case, the couples were out walking when the attackers approached them.
"It´s horrifying. One of the men produced a gun, pointed it at both victims and advised them to go to an alley. Both victims complied. They were forced to the ground. The male victim was forced to watch the female victim get sexually assaulted," police says.
