Patrick Mitchell's younger brother George 'The Penguin' Mitchell (68) is one of the most notorious crime bosses in the history of our State.
If he does return for his brother's funeral, it will be the first time he has been spotted back in his native city for many years.
Gardai have no warrant for his arrest so therefore he could not expect to be arrested, but the secretive gang boss is unlikely to be happy with any garda attention if he does decide to come home for his brother's funeral.
Patrick and George grew up together in extreme poverty and were first cousins of the late highly-respected former Fine Gael justice minister Jim Mitchell, who died in December 2002.
'The Penguin' is suspected of becoming a millionaire from his involvement in drugs trafficking from the early 1990s to the present day.
Mitchell has connections with the Kinahan cartel but also had links to Gerry 'The Monk' Hutch.
After the Regency Hotel bloodbath, it is understood that he made it clear to the Kinahan faction that he did not want to be dragged into the bloody feud, which has claimed up to 18 lives.
"Mitchell is too smart for that - he knows murder is bad for business," a senior source said last night.
It is understood that 'The Penguin' has been based between the Netherlands, Germany and Spain for a number of years where he is suspected of organising huge shipments of drugs from heroin to cannabis.
Back in the 1980s he had links to major league criminals such as John Gilligan and Martin 'The General' Cahill.
His son-in-law Derek 'Maradona' Dunne, who was one of Ireland's most notorious underworld figures, was shot dead in a row at his home in Amsterdam in 2000 - just one of a number of close associates of the crimelord to be murdered over the years.
However, 'The Penguin', who fled Ireland because of the garda crackdown on gangland in the aftermath of the murder of journalist Veronica Guerin in 1996, has never been targeted in a shooting.
He left for Amsterdam, where he had built up relationships with Dutch drug suppliers.
His departure followed that of his son-in-law, who had left Dublin after a dispute with another of the city's criminal gangs.
'The Penguin' became notorious in the criminal underworld after building up a massive ecstasy processing plant here more than 25 years ago.
Around that time, he was arrested by English police near Luton in possession of £575,000 cash, a down payment for a shipment of drugs. The money was seized but Mitchell was released without charge and has never served a serious jail sentence in his life.
