The authorities in Kenya have arrested at least three people after dozens of secondary school students were caught watching pornographic content on their business premises.

More than 50 pupils, who are from three different boys' schools in Nakuru, a town north-west of the capital Nairobi, were also detained on Wednesday, Kenya's Daily Nation newspaper reports.

According to the Standard newspaper, several video game shops were raided after a tip-off.

The suspects will be charged with operating an illegal business while the students will be given counselling, the paper says.
