A potentially deadly pipe bomb attack on a van owned by an innocent man is believed to be linked to the Kinahan-Hutch feud.
Detectives suspect the late night bomb incident - which sent one of the devices smashing through the window of a family home - is part of a "feud within a feud" in Dublin's north inner city.
Two viable pipe bombs were wrapped together and placed underneath the Ford Focus van that was then set on fire outside a house on Hawthorn Avenue in East Wall shortly after 11pm on Sunday.
A senior source told the Herald yesterday that "someone could easily have been killed" when one of the pipe bombs "took off like a missile" and went straight through the hall window of a house on the opposite side of the road.
The owner of the vehicle, a man in his 50s, has no involvement in the bitter gang warfare.
The house hit by the pipe bomb is also occupied by a "totally innocent family" who were uninjured when the bomb landed in their hall.
However, it is understood that the target of the attack was a 35-year-old man who is known to the van owner.
Rival criminals have blamed the 35-year-old for recent incidents in the area, which included a house being attacked and two vehicles being burned out.
Gardai have no evidence that these allegations are true and no arrests have been made in relation to the earlier incidents.
However, the bomb target has close links to the chief suspect - who is currently in jail - for the January feud murder of Jason 'Buda' Molyneux in the north inner city.
This link has made the 35-year-old a target for the Hutch mob.
Meanwhile, detectives are investigating one theory that the men behind Sunday night's pipe bomb attack were trying to frame one of Molyneux's closest pals for the incident.
Their getaway car was found burned out in the Fairview area, not far from the home of Molyneux's friend Gary Hanley.
"Hanley lives very near where the disguised two-man bomb attack team decided to burn out the car," a source said.
"This may well have been done so that Hanley would be blamed for the bomb attack, but gardai are confident enough that he was not involved.
"The bomb attack is linked to a feud within the wider feud which has been playing out in the East Wall area in recent weeks.
"There will be an increase in armed garda patrols in the locality to deal with this escalating situation."
Investigating officers and the Defence Forces' bomb disposal unit spent several hours at the scene investigating the attack in the early hours of yesterday.
Local people reported hearing two loud bangs before noticing that the van parked outside was on fire.
A fire extinguisher was used to douse the flames, but significant damage was done to the vehicle.
"A van was discovered on fire at this location and a number of items were discovered," said a garda spokesman.
"Defence Forces EOD were contacted and made safe a number of suspicious items which were believed to be viable devices.
"No arrests have been made and investigations are continuing."
The spokesman added that the devices found turned out to be pipe bombs.
