Mad Dogs biker gang confirmed as victims of M74 motorway attack

Mark 'Bruni' Brown, president of the Mad Dogs biker gang in Scotland, remains in hospital with serious injuries after a targeted attack was carried out by armed individuals on the M74 motorway. 

The incident happened at around 1pm on Sunday, August 2, between junctions 10 and 11 near Lesmahagow, when emergency services were called to reports of a disturbance involving a group of motorcyclists and people travelling in four vehicles.

The 63-year-old rider, along with other members of the club, was ambushed by the masked attackers who exited their vehicles with swords and bats, according to a report from the Daily Record. Brown suffered serious injuries as a result, but has vowed to fight on in a social media post that has since been deleted. 

Brown said this as part of the social media update:

“A bit of background to what has been going on with the dogs. This is NOT rumours or bulls***, just straight facts.

“To set it straight YES we were attacked on the M74 motorway by 12 masked and heavily armed cowardly cardboard gangster puppets with swords, bats and anything they could grab as a weapon.

“Here’s their version, ‘We are all in hospital and some of us are dead’. Clearly not, you incompetent cowards. You know what, we’re still standing and always will be!

“We have the same rights to drive on the roads as anyone else, doing what we want to do, but some people just can’t handle the fact we’re still here and growing stronger.”

Bruni and other members of the gang were believed to be travelling back from a weekend away in England, when the attack was carried out. 

According to Police Scotland, members of the public that witnessed the attack were left shaken, in what appears to have been a calculated and targeted attack. Surprisingly, this might not have be the first time that the two groups were involved in an incident, though, as the Daily Record also says the social media post referred to "previous incidents" between the two groups. 

Officers are still trying to trace some of the vehicles involved, although a red Mazda, believed to have been involved in the incident, was later recovered in Ayrshire with its rear window smashed.

Detectives are now appealing for witnesses, particularly anyone who was travelling on the M74 near Lesmahagow at the time of the incident. They're also asking anyone with dashcam footage, or who saw either the group of motorcycles or the vehicles before or after the attack, to come forward.

Anyone with information is asked to contact Police Scotland on 101, quoting incident reference 1458 of August 2, 2026, or anonymously through Crimestoppers on 0800 555 111.
