DUBLIN detectives have travelled to Spain to negotiate the handover of gangster 'Fat' Freddie Thompson. Sources say that gardai are spending a number of days with their Spanish counterparts examining evidence against Thompson. "This is standard procedure in a case like this," a source said. Thompson is due to appear before the High Court today where he is expected to apply for bail after being remanded in custody on Friday when he was arrested on a European Arrest Warrant. laundering Spanish authorities want to extradite him to Spain and they allege that Thompson operated as a bodyguard and chauffeur for the Christy Kinahan drugs organisation, which was targeted in a massive international police operation in May, 2010, known as Operation Shovel. Spanish authorities say that the Kinahan organisation is heavily involved in gun crime, drug trafficking and money laundering through a complex network of companies. Sources have revealed that in the weeks before his arrest, Thompson had fallen out of favour with the Kinahan mob -- organisation who his gang has been sourcing drugs from for over a decade. A European Arrest Warrant has also been issued for Thompson's close pal Gary Hutch (30) but gardai have not been able to find him. The Herald has previously revealed that Thompson's arrest warrant contains explosive details about a phone call tapped by Spanish police in December, 2009, between 'Fat' Freddie and Hutch in which the two criminals discuss firearms. The warrant also alleged that 'Fat' Freddie and Hutch travelled together to Portugal in November, 2009 and Amsterdam in May, 2010, to organise drug shipments. The warrant also states that Hutch and Thompson lived together in Spain and were "right-hand men" of Daniel Kinahan -- the son of Ireland's richest drugs trafficker Christy Kinahan. Also mentioned on the warrant is Ross Browning (27) from north inner city Dublin who is alleged to have collected a major Irish criminal from Malaga Airport in May, 2010, in a car which was also regularly used by the notorious criminal Hutch. violence Browning was one of around 30 people arrested by police investigating Kinahan's drug organisation last year. He was released without charge after being questioned for a number of days by Spanish authorities. Since being sent to Cloverhill Prison on Friday, Thompson has been placed in the protection unit in the jail because of fears that he may become a victim of a feud related attack or that he may orchestrate violence within the prison. It is understood he has had no visitors in jail.
