A woman at a Gas nightclub (Mumbai) on Saturday night was taken by 5 men,Who according to hospital and police reports, gang raped her before dumping her at Bandstand Mumbai. Unable to remember the events of the evening, tests later confirmed the repeat rapes along with traces of rohypnol in her blood.

Rohypnol , date rape drug is an essentially a small sterilization pill.

The drug is now being used by rapists at parties to rape AND sterilize their victims. All they have to do
is drop it into the girl's drink. The girl can't remember a thing the next morning, of all that had taken place the night before . Rohypnol, which dissolves in drinks just as easily, is such that the victim doesn't conceive from the rape and the rapist needn't worry about having a paternity test
identifying him months later.

The Drug's affects ARE NOT TEMPORARY - they are
PERMANENT. Any female that takes it WILL NEVER BE ABLE TO CONCEIVE . The weasels can get this drug from anyone who is in the vet school or any university. it's that easy, and Rohypnol is about to break out big on campuses everywhere.

Believe it or not, there are even sites on the Internet telling people how to use it. Please forward this to
everyone you know, especially girls.

Girls, be careful when you're out and don't leave your
drink unattended .

(added - Buy your own drinks, ensure bottles or cans received are Unopened or sealed; don't even taste
someone else's drink)

There was already been a report in Singapore of girls
drink been Spiked by Rohypnol.

Actually thats not true about Rohipnol(msking you sterile, it's street name Roofies).. It is actually used for severe amnsomnia in several countries and widely prescribed by doctors and used in hospitals.
