A takeaway boss in Carlisle has been jailed for 15 years after paying under-age girls for sex and inciting others to become child prostitutes.
Azad Miah, who is originally form Rochdale, 44, targeted his victims in what the prosecution at Carlisle Crown Court described as a "cold, clinical exploitation of the desperate and vulnerable".
The married father-of-four paid for the sexual services of two teenagers who were both introduced to him by the same woman.
One of those girls was encouraged to have sex with him out of desperation for cash when she was 15, while he had a sexual relationship with the other, a heroin addict, when she was aged between 15 and 17.
A jury also found the Bangladeshi national guilty on Monday of inciting three other girls, one as young as 12, into prostitution, while running a brothel above his former Spice of India shop in Carlisle city centre.
The court heard the 12-year-old complained to police on three occasions about him persistently harassing her in 2008, three years before his eventual arrest. She said she eventually gave up complaining because nothing was done.
Judge Peter Hughes QC said police needed to learn lessons from not heeding her complaint and that there were a number of "missed opportunities".
Detective Inspector Geoff Huddleston, who led the investigation, said: "We acknowledge that some of the victims did make contact with police about concerns over employees at the Spice of India takeaway before the full police investigation was launched.
"However, the information given to police was not clear so the true picture of what was happening was not disclosed."
Miah was jailed for a total of nine years for four counts of paying for the sexual services of a child between 2006 and 2009, one year for keeping a brothel between 2005 and 2011 and five years for five counts of inciting child prostitution. He was cleared of child prostitution allegations relating to two other girls.
Police are investigating whether he had links with nine men from Rochdale who were jailed for child sex offences last week.
