The government of Lagos state in Nigeria is cracking down on street vendors.
The authorities are enforcing a previously widely-flouted law.
Street hawkers and those who buy from them face a fine of more than $300, or six months in jail.
A BBC correspondent in Lagos says there are far fewer hawkers in the streets today than usual because they are scared of being arrested.
Many hawkers have complained that if they are not able to work, they will not be able to support themselves.
