AN “untouchable” traveller gang behind violent robberies, drug deals and ATM thefts has been jailed for a total of 35 years.

The brazen criminals conducted a reign of terror in South Yorkshire, funding their criminal activities through producing vast amounts of heroin in residential homes.

Yesterday at Sheffield Crown Court the “violent and unpredictable” gang was finally brought to justice after cops uncovered “multiple kilogrammes” of the Class A drug.

They also unearthed a host of weapons including an Uzi-style machine gun, two revolvers, two semi-automatic guns and ammunition – many of these at a travellers’ site in Doncaster.

Around £115,000 in cash was also seized from another travellers’ site in Amthorpe.

The gang’s activities – which included firearms discharges and violent knife attacks – came to light after cops carried out targeted work around organised crime in the area.

Through Operation Railbird police then made a series of arrests between January and October 2016 after seizing drugs and 100 bladed weapons including machetes.

Detective Inspector Lee Fletcher said: “The behaviour of this group was incredibly dangerous and linked to feuding with a rival organised crime group.

“But the escalation of violence experienced in late 2015 posed a significant risk for serious harm and even death within local communities.”

Eight defendants admitted conspiracy to supply Class A drugs, namely heroin.

Tommy Lee Smith, 38, of Doncaster was jailed for 12 years.
