According to sify.com:
Some 300 sex workers from El Trocadero, a well-known brothel in the Peruvian port of Callao, demonstrated against foreigners entering the business.
Prostitution is legal in Peru for adult women, but they must register with municipal governments and carry health certificates, while brothels require licenses.
The protesters are apparently quite serious.
Chanal 4 television aired shots showing how a picket of prostitutes kicked their way into their colleagues’ rooms to make them join the protest in Callao, which sits next to the Peruvian capital.
The foreigners are undercutting the going rate!
‘An hour costs 120 sols ($42), but for them (the foreign prostitutes) no; since they’re desperate to make some money, they only charge 80 sols ($28) per hour,’ Bella said.
And they are sneaky!
‘There are foreign women coming here as tourists and then they decide to work and just ruin the place,’ another protester said.
