Three Peterborough criminals have been given lengthy jail sentences for their role in a major drug dealing network.
Ayleasha Bennett, Sharon Bowle and Richard Aguis were all locked up with eight others - including three members of the same family from Elm - at Cambridge Crown Court.
The court heard the network distributed millions of pounds of heroin across the country.
The operation was run by 41-year-old David Warden, with help from his mother Mavis, 63, and father Barry, 69.
The quantities they were running was revealed when one supplier, Usman Iqbal, 22, of Thornbury Avenue, Bradford, was arrested on 29 December 2013 near Wittering.
He was found to have 4kg of heroin in his car, worth an estimated £400,000, and was jailed at Peterborough Crown Court in April for four years and nine months after pleading guilty to possession of heroin with intent to supply.
Bennett (28), of Albany Walk, Peterborough, was jailed for nine years, Bowles (44) of Howland, Peterborough was jailed for three years and nine months and Aguis (50) of Toftland, Peterborough was jailed for seven years and four months.
Senior investigating officer Detective Chief Inspector Becky Tipping said an estimated £4 million worth of class A drugs had been handled by the network during the course of the investigation, which ran from September last year to June this year.
She said: “The Wardens were running a significant drugs distribution enterprise from their home and directed others who shipped in drugs from West Yorkshire to be distributed in Cambridgeshire.
“This was a complex investigation carried out by a dedicated team and I hope the sentences handed out today serve as a warning to others involved in the drugs trade.
David Warden was jailed for 12 years, while his parents, who were jailed in May 2005 for a similar drugs conspiracy run from the same address, were sentenced to six years and nine months, for Mavis, and three years and 364 days for Barry.
Michael Thompson, 26, of Eighth Avenue, Wisbech, was sentenced to four years. Mohammed Idris, (38), of High Street, Dewsbury was jailed for six years and six months.
Connie Smithee, 26, of Harrys Way, Wisbech, was jailed for three years and six months while Chanel Bennett, 19, of Bedford Court, Thorney, Peterborough, was jailed for three years and nine months.
Four others will be sentenced in the new year,
