HOUSTON (KTRK) -- A five month undercover investigation into drug activity at the teen night club, Kryptonite, led to a raid late Friday night. Some of the people inside were as young as 15.



"The cops came in messing with everybody, threw us against the wall," says a young man who identified himself as Travis.



"They shouldn't be able to do this. Ain't no drugs in there," adds Michael Pridemore.



Images we captured on camera tell a different story. Harris County Precinct One Constable Alan Rosen says undercover officers saw and participated in numerous drug buys leading up to the raid.



"There was cocaine, acid, mollies, marijuana, ecstasy," Rosen says of the moments following the raid. "It was all thrown on the ground."



Constable Rosen says the drugs were packaged to sell. Four staff members were arrested.



"They helped facilitate some of the drug transactions that took place."



He believes more was going on here, including possible sexual assaults.



"When we initially got word of this club and started the investigation, we were told there was a rape cave where people that visited the club were given a drug like a date rape drug and then brought into this dark room and sexually assaulted."



Philip Carvell owns the Brewery Tap a few doors down.



"It has happened in the past a few years ago. But these guys that are running it now are good guys," Carvell says. "So I'm kind of surprised that that it was as much drugs as was down there supposedly."



Constable Rosen calls the club a nuisance, and says it should either be shut down, or the owners should step up and be more responsible for what happens in their establishment.



Constable Rosen is asking anyone who may have been a victim of sexual assault in the club to call his office. That number is 713-755-7628.
