Kingpin Ross McGill’s Tamo Junto (TMJ) thugs launched a firebomb attack on Edinburgh business linked to mob boss Mark Richardson’s pal.
The Garage Conversion Company on The Wisp was targeted in the early hours of Tuesday morning.
Police Scotland confirmed the fire was deliberate.
The unit is owned by Derek Welsh, whose wife Mercedes McMillan is a relative of Mark Richardson’s close pal David McMillan Snr.
Welsh is listed on Companies House as holding directorship in 10 firms across Edinburgh and East Lothian.
McMillan Snr, 55, has previously been targeted at his plush home in Pitcairn Grove in the capital a number of times in incidents linked to Scotland’s gang war.

Pictures from the scene on Tuesday show a police vehicle parked outside the gates of the business as two uniformed officers sit inside.
The front door of the building appears to have been set on fire, with the wall above it charred.

Two smaller doors to the left also appear to have been torched and the walls inside both scorched. It is unclear if the blaze spread inside the property.
McGill, 32, launched a gang war in Scotland last year after blaming Richardson’s crew for paying for a £500,000 consignment of cocaine using fake bank notes.
His pal David McMillan was targeted at his home at Pitcairn Grove on April 17 last year when two masked thugs torched his front door while children were sleeping inside.
He was targeted again weeks later when his Land Rover was firebombed on his driveway on May 7.
McMillan was left with a serious injuries when a gang of three men wearing balaclavas turned up outside his home and attacked him with machetes on May 22.
Arran Reid, 27, was convicted for his role in the attack and sentenced to eight years and four months back in December.
Anthony Brown, 50, was slapped with five years last month and will be supervised for a further three years on his release.
The getaway driver – 21-year-old Joshua Stewart – was caged for three years and eight months.

McGill’s TMJ crew also targeted the Daniel crime clan in Glasgow due to their association with Richardson.
High-ranking members of the family, including Steven ‘Bonzo’ Daniel, 46, and Norman ‘Snudge’ Daniel, 73, had their home torched.
The Lyons mob helped McGill by supplying him with information on targets within the Daniel family.
The violence culminated at the end of May when Ross Monaghan, 43, and Eddie Lyons, 46, were executed outside a pub in the Costa Del Sol.
Steven Lyons, 46, was arrested on an Interpol Red Notice in Bali at the end of March and a fresh wave of violence erupted, with gangsters within Richardson’s mob and the Daniel family being targeted over the past two months.
A Police Scotland spokesperson said: “Around 2.15am on Tuesday, 16 June, 2026, officers received a report of a fire at a premises on The Wisp, Edinburgh.
“The fire is being treated as wilful and enquiries are ongoing.”
