Tanzania is holding about 500 
suspected sex workers and nearly 300 of their alleged customers in 
detention as part of a crackdown on prostitution.
The first 
suspects will start appearing in court on Wednesday, Dar es Salaam's 
deputy police commissioner told the BBC, confirming the arrests.
Rights
 groups have condemned the arrests, which started a week ago, urging 
police not to hold suspects beyond the legal 48-hour limit.
Prostitution is illegal in Tanzania.
 Tanzania's new President John Magufuli, who came to power on an 
anti-corruption platform, has previously criticised prostitution in the 
country.
