By going above and beyond the call of duty, however, the two undercover officers were able to expose a prostitution ring stretching from Stockholm north to Gävle in eastern Sweden, the Metro newspaper reports.
A 60-year-old Stockholm resident has been charged on suspicions of running brothels in five massage parlors.
The brothels were discovered after two male police officers working undercover visited two separate massage parlors and agreed to take their clothes off.
After stripping, each officer was offered “extra” genital treatment.
“An unusual, but legal method of investigation,” said one of the officers.
In addition to the 60-year-old, a 27-year-old woman and a 32-year-old man were also charged for the extensive pimping operation.
