The second Formula E event at the Berlin E-Prix was delayed by seven minutes due to a protest just before the start of the race by activists.
As the first cars did their normal burn out to get into their starting positions from the dummy grid, four people, two men and two women, got onto the track and appeared to pour something on the circuit according to race director Scot Elkins.
One of the protesters allegedly glued themselves to the medical car. On one of the T-shirts, the phrase “stop the fossil fuel madness” was written and on another protester, the words “for us all” were transcribed.
Security took them away and everyone came away unharmed.
A Formula E spokesperson told Total-Motorsport.com: “The race was temporarily delayed while local authorities responded to a protest action unrelated to the event.
“Security services quickly and safely contained the disruption. The event was able to proceed as planned.”
The incident comes less than a week on from Just Stop Oil activists making a protest at the World Snooker Championship in Sheffield.
A 52-year-old man and 30-year-old woman were arrested on suspicion of criminal damage, with the former pouring orange powder on one of the tables which stopped play for the rest of the night on one side of the Crucible.
