An investigation has started into the cause of a fire which destroyed a Hull community centre.
The fire broke out in the two-storey building at the North Hull Adventure Playground on Cottingham Road just after 2100 BST on Wednesday.
Fire crews were called back to the scene on Thursday after reports the building was back alight.
Humberside Police are investigating the incident, though it is not yet known how the fire started.
"The police helicopter radioed through at 2109 BST to say that a fire had been spotted in the Cottingham Road area," a spokeswoman told BBC News Online.
"The fire brigade were contacted and police and fire officers attended the scene.
"Until we know exactly how its started we are classing it as a fire of doubtful origin."
