A theater in the Rotterdam amusement park Plaswijckpark burnt out on Wednesday evening.
Police have arrested a minor suspect for arson.
The fire broke out during the evening.
The fire spread quickly through the thatched roof of the building.
The fire was under control around 9.30 pm.
A video is circulating on the internet in which there may be arson.
After investigating those images, the police managed to track down and arrest the suspect.
Plaswijckpark is an indoor and outdoor playground and is located in the north of Rotterdam, in Hillegersberg.
The park says it is inundated with statements of support on Facebook.
"We are very grateful to you for that."
The theater building included a catering facility.
Fortunately, there were no injuries and the animals were brought to safety, the park continues.
"We will of course give you an update when there is more clarity."
Shortly after the fire, a crowdfunding campaign was started for the park.
Almost 37,000 euros has already been received there around 07:00.
