The fire began just before midnight and a number of people saw it and called 111.

It took 40 firefighters five hours to put the flames out.

Fire and Emergency shift manager Paul Redden said the top floor of a two-storey block was well alight when trucks arrived.

A fire investigator is also at the school this morning.
