Can Senegal stop school beggars?

Senegal's President Macky Sall has given orders to remove begging children from the capital's streets where an estimated 30,000 minors beg each day.

The country is 95% Muslim and child begging is often organised by Koranic teachers, making the practice particularly hard to curtail. BBC Africa’s Maud Jullien in Dakar followed the undercover police on their patrol in search for children.
