Two men convicted of controlling prostitution for gain in Manchester are wanted by police to be recalled to prison, GMP have said.
Jin Cheng, 41, and Ye Lin, 39, both have links to south Manchester and the city centre.
They were jailed last month for their role in booking and paying sex workers.
A judge at Manchester Crown Court was told young women were exploited.
Cheng was jailed for 11 months and Lin for eight months.
But both were released from custody as they had already served half of their sentences while on remand ahead of trial.
Both Cheng and Lin were due to stand trial but pleaded guilty to the offence of controlling prostitution for gain.
Now Greater Manchester Police have published appeals urging the public to come forward with any information surrounding the two brothel workers' whereabouts.
Cheng, said GMP, has breached the terms of his license.
Both men also have links to London.
Manchester Crown Court heard both men arranged clients' meetings and created online adverts - charging £160 for an hour and £500 for nine hours.
Detectives from GMP's Serious and Organised Crime unit stormed a flat on Harter Street in the city centre in August 2019.
They believed the property was being used as a brothel.
Among items discovered were condoms, baby oil, clean towels and bedding, the court heard.
Three young sex workers were found at the flat.
Anyone with information regarding the whereabouts of both men is being asked to contact police on 0161 856 4102 or Crimestoppers on 0800 555 111.
