At the London art institution Royal Academy, climate activists have glued themselves to a painting.
Police arrested two people, according to the Times newspaper.
According to the report, the group belongs to "Just Stop Oil" and is campaigning against the new production of oil and gas.
The activists announced that an important art institution had again been shaken in an "act of civil disobedience".
Accordingly, five supporters stuck to the painting.
Pictures show that one of them sprayed "No new oil" on the wall under the picture.
The government is urged not to issue new oil or gas licenses.
At the end of June, two members of the initiative glued their hands to the frame of a painting by Vincent van Gogh.
"We don't want to do this here," says one of the two, 21-year-old Louis McKechnie, in a video.
"We're stuck here on this painting - this beautiful painting - because we fear for our future."
The painting "The Last Supper" in the Royal Academy is a copy of Leonardo da Vinci's world-famous work.
The copy is attributed to Da Vinci's pupil Giampietrino.
The original mural can be seen in the Santa Maria delle Grazie monastery in Milan.
