Police are appealing for any footage captured on mobile phones following three arsons at schools and village halls around Broadland.
Around 9.30pm on December 21 a bin lid was set on fire at Taverham Village Hall on Sandy Lane. At Firside Middle School on Middletons Lane in Hellesdon around 6.50pm on December 18 two cones in a wheelbarrow were set on fire.
And two cones near a dugout at Horsford Village Hall were set alight at some time on December 19.
It comes after Norfolk Fire and Rescue Service issued a warning following more than 20 arsons in North and West Norwich in recent weeks.
Norwich district commander Duncan Ashworth said: 'Even a small rubbish fire can lead to serious consequences, particularly in a commercial context as many businesses are unable to recover from an arson attack.
Anyone with any information should contact Norfolk Police on 101.
