A car is seen jutting out from the side of the building which has now been sealed off by a police cordon.
Separate videos show the man pouring a clear liquid on to the tarmac before sending it up in flames as horrified witnesses watch.
Video taken from the scene and posted on social media shortly after 7pm records a witness saying a car careered into the station.
Councillor Ergin Erbil tweeted: ‘Reports of major incident declared at Edmonton Green police station. If you’re in the Fore Street area stay safe and be careful.’
