Gardai are closely monitoring the activities of a Co Meath car dealership which is suspected of being used to launder large amounts of drugs cash for one of the gangs involved in the deadly Drogheda feud.
Sources say that "business is booming" at the dealership, which is run by a convicted criminal aged in his 40s.
"This fella has previously served a significant jail sentence but has kept his head down in recent years," a source told the Herald.
"He is not directly involved in the Drogheda feud, but some of his close associates would be criminals who were previously directing activities for the so-called anti-Maguire faction in the deadly dispute.
"It is suspected that they have pumped big money into the car dealership, which has been going from strength to strength in recent months."
The business, which cannot be named here for legal reasons, has not yet been raided by the Criminal Assets Bureau (CAB).
Slain crime lord Richie Carberry, who was shot dead last November at his home in Bettystown, was also linked to the garage - his was one of four murders linked to the feud.
"This is a place that has a lot of stock and there have been big questions asked as to how it was funded," a source said.
"Hundreds of thousands of euro has been invested into it.
"It is being investigated that money from serious drugs trafficking in Louth and Meath, as well as north Dublin, is being pumped into the place."
The business is closely linked to a 42-year-old criminal, originally from Donaghmede, who is believed to be the link between the young Drogheda mob behind the gruesome murder of Keane Mulready-Woods (17) in January and larger crime groups in the capital.
Gardai observed the 42-year-old gang boss drinking with slain Robbie Lawlor - who was the chief suspect in Keane's murder - in a Drogheda pub just days after the teenager was kidnapped and dismembered.
His plush home was later raided by detectives investigating the murder after they received information that Lawlor had visited his home before and after the shocking crime.
The suspected drug trafficker has been a major target for local and national garda units for running a criminal enterprise across Leinster.
Car dealerships are traditionally a favourite way for Irish gangs to launder money.
Last month, the Herald revealed that one of Ireland's most prolific crime gangs invested almost €1.5m of drugs money into a legitimate high-end car dealership.
In that case, 'The Family' gang employed a car dealer who was struggling with alcohol and cocaine addictions to run the business.
They have been using Dublin garages to launder money for years, and three years ago the CAB raided five car dealerships linked to the gang.
