Gang boss 'Fat' Freddie Thompson has left Ireland after spending over a week in Dublin.
Thompson (30) flew back to England, where he has been spending a lot of time in the Birmingham area, it is understood.
'Fat' Freddie was back in Dublin last week for the birth of his nephew Jamie, who was born to Thompson's sister Lisa Jane in the Rotunda Hospital.
His visit was monitored by gardai and Thompson was spotted in a number of pubs in the Crumlin area.
It is understood the gangster -- who is said to be wary of the tough anti-gangland legislation which was introduced by the last government in 2009 -- kept an extremely low profile.
However Thompson was seen a number of times in the company of his girlfriend Vicky Dempsey's brother, Karl.
Associates of Dempsey are believed to have been involved in a shocking double murder in 2007.
Dempsey (33), of Stanaway Road, Crumlin, was jailed for seven years in 2000 after being caught with IR£50,000 in October, 1998. He was arrested after a lengthy operation by the Garda National Drugs Unit who arrested him at the Mill Shopping Centre, Clondalkin.
Dempsey had taken a black plastic bag out of his pocket, thrown it on the floor, and attempted to run away. The bag contained about five ounces of heroin.
In March 2002, the Criminal Assets Bureau secured judgment for €424,987 from Dempsey for income tax and interest due on foot of a final assessment for the three years up to April 5, 1999.
Following a series of hearings in the High Court, CAB obtained the judgment.
Lawyers for Dempsey had argued that a sequence of correspondence between his solicitor and CAB was a sufficient invocation of the appeal procedure of the 1997 Taxes Consolidation Act.
