Peterborough City Council's Chief Executive Gillian Beasley said: “Listening to the catalogue of crimes committed against these children has been absolutely devastating and we wish they could have been rescued sooner.
“But it was not until our social workers and the police gained the trust of the victims, so they felt able to tell us the full extent of what was happening, that the police were able to arrest the criminals who were responsible.
“We are pleased that we have seen justice done today. We would also like to pay tribute to the victims. Without their courage to stand up in court we could never have secured these convictions
“We have also called for a serious case review. We will be working closely with that review and we look forward to the findings.
“No one is more determined than us to stop criminals like these preying on our children and we will be sharing everything we have learned with colleagues around the country."
“Peterborough will be a safer place today, especially for vulnerable young women.
"The guilty verdicts send out a signal that British justice has been done and that this criminal behaviour is completely unacceptable and should not be tolerated in any community, including the Roma community.
"The statutory agencies in Peterborough, particularly the City Council and Cambridgeshire Police, have worked well together in dealing with these appalling crimes and their victims but there are important lessons to be learnt at how we protect vulnerable young women from predatory paedophiles...
"We need to redouble efforts to ensure that immigrants from EU countries are working, contributing and paying taxes and if not they should be removed from the UK with urgency if participating in criminal conduct.
"I will be writing to the Secretary of State for Justice to ensure that these foreign convicted criminals are permanently deported on release from custody.”
