A European arrest warrant has been issued for gang boss 'Fat' Freddie Thompson in connection with violent disorder following a pub row in Dublin last year.
The 32-year-old is currently on bail in Spain and being investigated there after police linked him to the organised crime empire of Christy Kinahan.
Detectives suspect Thompson worked for cocaine cartel controller Kinahan, dealing his drugs and laundering money.
The Spanish authorities want to question him in relation to three specific offences: participation in an organised crime gang, arms trafficking and drugs trafficking.
Up to 30 members of the Kinahan mob were arrested by Spanish police in May 2010 under Operation Shovel.
While Thompson was not in Spain at the time Kinahan's gang were lifted, gardai arrested him here and sent him back in October 2011.
He was allowed to return to Dublin at the start of last year.
While here, he was in a south city pub on January 7 following the funeral of gangland murder victim Christy Warren when he is alleged to have thrown a bottle at a customer and punched him. He is also accused of attacking two women at the bar and could face up to 10 years behind bars if convicted.
Although no complaint was made to gardai, a warrant has been issued and Thompson is likely to be questioned as a result.
He is likely to be arrested in Spain this week and flown home to face the charges.
Thompson ruled half of the vicious Crumlin-Drimnagh fighting factions that has claimed 17 lives in Dublin since 2001.
He was rumoured to be travelling to Dublin at the weekend for a wedding but did not show. Neither was he present at the funeral of an uncle who died in jail after Christmas.
Thompson is said to have married his partner Vicky Dempsey over New Year.
