after spraying orange paint

2 climate activists were arrested after spraying orange paint on
Stonehenge
...
...
The group said the orange cornflour used on the monument would wash
away in the rain.
...
...
The action took place just one day before the summer solstice -- the
longest day of the year --- when thousands of people are expected to
descend upon the historic monument.
...
...
It's the latest public protest initiated by activists with Just Stop
Oil, whose members have also interrupted tennis matches at Wimbledon,
disrupted the London pride parade and defacedclassic works of art.
