Residents of Githurai 44 were in shock as Â five men suspected to be members of a gang behind a series of rape incidences were arrested from a forest in the area.
The police also discovered a cave in the forest that had a number of clothing indicating that a number of people lived there.
â€œWe also recovered tens of female underpants and several pornographic materials in the cave and we suspect that several people have been involved in a rape syndicateâ€ a resident involved in the operation, Robert Mwangi said.
He said the cave also had had sharp objects like knives, purportedly used to intimidate the suspectâ€™s victims to give in.
â€œWe decided to be involved in the search for the criminals because several females from our area and others, have on several occasions been raped in the areaâ€ Mr Mwangi said.
The assorted pornographic materials were arranged in an album and were placed under what seemed to be a sleeping area inside the dark cave.
The five suspects are being held at the Kiamumbi police station as detectives continue with their investigations. The suspects are aged between 22 and 36 years.
