Dutch police are reported to be looking for a 'scooter youth' after a stack of tyres were set on fire at the newly revamped Zandvoort circuit on Tuesday evening.
The tyres were among the stockpile that would have been used to augment barrier protection during a race.
The fire sent thick plumes of black smoke high into the air which could be seen for miles around. Fire crews were quickly on the scene and eventually brought the blaze under control.
According to GPfans.com, circuit director Robert van Overdijk told local newspaper Haarlems Dagblad that the fire had been started by what he described as a "scooter youth".
News reports said that Dutch police are currently seeking witnesses to the incident. It's not believed that any part of the track or the supporting facilities were damaged in any way by the fire.
F1 had been planning on returning to the coastal circuit after a 35 year absence, but the Dutch Grand Prix was among the races to be indefinitely postponed due to the coronavirus pandemic.
Organisers subsequently confirmed that the race would not be rescheduled in 2020. Rather than holding a race behind closed doors, organisers felt it would be better to wait until 2021 before Zandvoort took up its place on the calendar.
"We would like to celebrate this moment, the return of Formula 1 in Zandvoort, together with our racing fans in the Netherlands," former F1 driver and Dutch Grand Prix sports director Jan Lammers said last month.
"We ask everyone to be patient. I had to look forward to it for 35 years, so I can wait another year."
