A British paedophile who preyed on vulnerable Kenyan children was caught after a holidaymaker used ‘gut instinct’ to report him to authorities.

Keith Morris, from Hull, travelled to a rural village in Kilifi County over a period of about 20 years, and met with groups of young girls, but was flagged to the National Crime Agency by David Bushell after the tourist believed something was "seriously wrong."

Bushell, from London, said that he observed Morris over three days after spotting the 72-year-old with groups of girls aged between 10 and 12.

Speaking to the BBC, he said: "I felt like something was wrong but I was not really sure why the alarm bells were ringing.

"By the second day I felt like I just wanted to go and confront him and ask 'What are you doing with these children? What relationship are they to you?'”
