Bailed: Dane Bower, pictured in London earlier this year, was released on bail pending further enquiries
Celebrity Big Brother star Dane Bowers has been arrested in connection with a suspected Mephedrone drug ring.
The singer, 30, was quizzed by detectives this week after £650,000 of the party drug, often known as 'Meow Meow' , was found in Manchester.
Police have been working undercover investigating a group of cagefighters for the past five months.
Mr Bowers is part of the KnuckleUp promotions team, who organise Mixed Martial Arts (MMA) fights across the country.
Officers swooped on several addresses in Manchester after receiving tip-offs that the Class B drug was allegedly being sold at KnuckleUp events.
The DJ, who famously dated Katie Price in the early Noughties, handed himself into police in his hometown of Croydon, Surrey, and was released on bail pending further enquiries.
A spokeswoman for Greater Manchester Police said: 'On Tuesday November 16 officers from Greater Manchester Police arrested seven people on suspicion of conspiring to supply drugs.
'A 30-year-old man from Croydon, a 31-year-old man from Somerset, a 25-year-old woman from Bolton and a 46-year-old man from Staffordshire were bailed until January 11, 2011.'
Asaf Mahmood, 22, of Salford, Mohammed Ikram Kibria, 28, from Rochdale and Shiraz Shah, 28, of Whalley Range, were charged with conspiracy to supply drugs.
Mephedrone was made illegal in April this year, becoming classified as a Class B drug.
Anyone found in possession of mephedrone now faces five years in prison. The maximum sentence for dealing in the drug is 14 years.
Now working in music, as well as with KnuckleUp, Bowers found fame in late Nineties boy band Another Leve, who enjoyed seven top 10 hits.
