Protestors descended a Scots oil terminal in a bid to stop upcoming oil and gas projects.
Just Stop Oil blockaded Nustar Clydebank in West Dunbartonshire in the early hours of Tuesday morning, having arrived at around 4am.
Around 40 young climate activists took part in the demo, sitting on top of pipes and on silos while others headed into the terminal itself.
The group want the UK Government to prevent any new oil and gas projects getting the go-ahead.
Just Stop Oil started blockading fuel terminals in England on April 1, with action south of the border has seen more that 1,000 arrests.
Tuesday morning's protest was the first of its kind in Scotland.
Neil Rothnie, 69, a retired offshore oil and gas worker from Glasgow, said: "North Sea oil and gas does not offer energy security.
"The North Sea oil and gas industry has one priority and it is not the climate crisis.
"It's not the future of North Sea oil and gas workers.
"And it's certainly not whether the poor can stay warm. If the Government was serious about a just transition, we would be seeing it here in Scotland."
He added: "Where are the turbine factories in Scotland?
"Where are the yards building platforms for offshore wind?
"Where are the projects to properly insulate our houses?
"When will we get free public transport?"
A Police Scotland spokesman said: "Officers are currently engaging with a group of people who are carrying out a protest at Rothesay Dock in Clydebank, which was reported to police around 4.10am on Tuesday, May 3.
"Police Scotland is a rights-based organisation that puts our values of integrity, fairness, respect and a commitment to upholding human rights at the heart of everything we do.
"This means that we will protect the rights of people who wish to peacefully protest or counter-protest, balanced against the rights of the wider community."
The UK Government has been approached for comment.
