A hospital in northern Nigeria has withdrawn 30 graduates' job offers after they tests positive for hard drugs. They had been shortlisted for jobs at the National Orthopaedic Hospital in the northern city of Kano.
They were among 150 people employed from thousands of applicants.
A spokesman for the hospital told me that they introduced the procedure in the latest recruitment drive to ensure that only mentally sound people are employed because of the sensitive nature of the medical profession.
The authorities have not given details of the types of drugs the new employees tested positive for. Some local media reports say the people who failed the drugs tests were furious.
