Scores of armed and uniformed gardai kept watch outside the home of murder victim Vinny Ryan last night as his remains were waked inside.
At least 10 undercover detective units patrolled the roads around the family home in Donaghmede, while further uniformed gardai kept a visible presence in the area.
Armed members of the Special Detective Unit (SDU) also kept a discreet presence nearby, in what sources have previously described as a "matter of precaution" to prevent any further violence.
Senior gardai are believed to have authorised the heavy garda presence in an attempt to prevent any potential repeat of the controversial display that occurred at a previous funeral.
The 25-year-old's brother Alan was buried amid a Republican and military display at his Donaghmede funeral in 2012.
A group of paramilitaries dressed in green fatigues with their faces covered fired a number of shot's over Alan Ryan's coffin as his body was transferred from the family home to The Church of the Holy Trinity.
However, yesterday's wake passed off without incident.
Vinny Ryan's remains were brought to his home address in the early afternoon, while scores of mourners slowly began to file in to the house as the day wore on to pay their respects.
His funeral will take place at 10am at the same church in which his brother was buried four years ago, before he is brought to Fingal Cemetery for burial.
Gardai are continuing to investigate the murder of the father of one, but no arrests have yet been made.
Detectives are investigating whether an organised crime gang led by a drug dealer known as 'Mr Big' is behind the killing.
The drug trafficker's gang are the prime suspects in the murder of Alan Ryan, and the victim's family have also blamed him for the latest murder.
Gardai are continuing to investigate whether 'Mr Big' was involved in the murder of Vinny Ryan, as well as examining a host of other "complicated theories" in connection to his death.
Ryan was sitting in his white Volkswagen Golf on McKee Road when he was blasted by a hit team. A silver Volkswagen Golf which gardai believe was used in the shooting was later found burnt out in the Co Kildare area. It had previously been stolen in a burglary in October from the Kildare region.
In his death notice, Vinny Ryan was described as devoted to baby Phoenix and partner Kelly. He is also survived by his mother Marion and siblings Anthony, Niamh, Dermot and Eoin.
