Police in Tanzania say they have arrested a Kenyan national who was attempting to sell an albino man.

The arrest was made in a sting operation as police pretended to be businessmen buying albino body parts.

Police say they struck a deal equivalent to more than $250,000 (£159,000) for the 20-year-old man.

In Tanzania, the body parts of people living with albinism are used by witchdoctors for potions which they tell clients will help make them rich or healthy.

Over the last three years more than 50 albino adults and children have been killed. The Tanzanian government promised to take action, and there have been some court cases.

But justice is slow.
