Eco vigilantes targeting 4x4s and SUVs have set their sights on Glasgow.
Vandals calling themselves " The Tyre Extinguishers " deflated tyres in posh parts of Edinburgh in a move branded "reckless" by cops.
They claimed to have deflated the tyres of around 20 SUVs in Edinburgh in the early hours of Sunday, in a bid to "make it impossible" to own such cars in cities.
It came just days after they claimed to have hit around 100 of the vehicles across the capital.
And now it seems that the climate campaigners are planning to take the movement down the M8.
In a tweet posted yesterday, the group mentioned Glasgow - and begged for volunteers.
A Twitter post said: "SUVs disarmed in the posh Bruntsfield area last night. Brighton, London, Bristol - looks like Edinburgh is coming for your record! Where's Glasgow at??"
In another tweet, they asked: "Where are our Glasgow people at? Want to get involved? Email us at tyreextinguishers@riseup.net."
In total, the group estimates they have deflated tyres on around 200 cars in Edinburgh since March, and have also targeted vehicles in Dundee.
Similar attacks took place in Glasgow when COP26 was being held in the city last November and flyers were left on the targeted cars by anonymous protestors.
A spokesman for the group said: "We are defending ourselves against climate change, air pollution and unsafe drivers.
"We do this with a simple tactic: Deflating the tyres of these massive, unnecessary vehicles, causing inconvenience for their owners.
"Deflating tyres repeatedly and encouraging others to do the same will turn the minor inconvenience of a flat tyre into a giant obstacle for driving massive killer vehicles around our streets.
"We're taking this action because governments and politicians have failed to protect us from these huge vehicles. Everyone hates them, apart from the people who drive them."
Police Scotland said they received several reports of tyres being deflated.
Superintendent Mark Rennie said: "We have received a number of reports of vehicle tyres being deliberately deflated in the Edinburgh area.
"This is a reckless and potentially dangerous act which could put drivers and road users at risk.
"Enquiries are ongoing and we would encourage members of the public to call us immediately if they see anyone acting suspiciously close to parked vehicles.
"I would also urge all drivers to check their vehicle before setting off and to contact the police on 101 should they suspect their vehicle has been tampered with."
