Lancaster police said they arrested three men during a prostitution sting Thursday in the southwest area of the city.
Police said female undercover officers posed as prostitutes, and in each arrest the officer was offered money in exchange for a sexual act.
Authorities identified those arrested as James Sellard Jr., 49, and Rodney Ware, 47, both of Lancaster, and Luis Fonseca, 46, of Havertown.
Each was arrested on a charge of criminal solicitation and released after processing.
Police said they will continue to target prostitution related offenses over the next several months.
They said the sting operations are in response to citizen and business owner complaints about prostitution occurring in plain view.
