The sister of missing British explorer, Chris Velten, has released further information about his rumoured whereabouts in another push to find him.
Chris, from East Sussex, was last seen in Bamako, Mali in March 2003 as he set off to retrace the journey taken more than 200 years previously by Scottish explorer Mungo Park.
The Edinburgh University graduate, who was 28 at the time, planned to follow the 2500-mile route, planning to cross West Africa by foot and canoe before following the River Niger through Mali, Niger and Nigeria in a canoe.
Now, Chris’ sister Hannah has posted a series of photographs taken of Chris between 2001-2003 in the hope that someone will recognise her brother who the family believe is in Nairobi.
He is described as being 5’10” tall with brown eyes, a slightly broken nose and a mole on the back of his neck.
His family think he is living locals under the radar in or around Nairobi and it is thought that he is likely to have suffered from malaria and could have or still be suffering from amnesia.
His sister also believes he is likely to be working with children, or will have youngsters around him.
“Chris will probably be being looked after, to some degree, as we think he will be physically and emotionally fragile.”, Hannah posted.
One Facebook posted suggested that the pictures looked familiar and the family should look around Githurai 45 (Ruiru).
