Part of the school was severely damaged in the attack

Term at Rhyl High School was due to start on 5 September, but damage caused by the blaze on 12 August has meant that the school will remain closed.

Twenty-two temporary classrooms are being set up and pupils will instead begin the school year on 12 September.

A police investigation into the fire is continuing.

Three floors of block three at the school were damaged by fire and smoke during the fire, which started at around 0240 BST on 12 August.

'Delay opening'

Four fire crews brought the blaze under control by 0500 BST.

Denbighshire Council said damage to the inside of the school was extensive and the area affected would remain closed until all rebuilding and refurbishing works had been carried out.

It added that 22 temporary classrooms would be set up for the new start of term at the school.

Dewi Owens, cabinet lead member for lifelong learning, said: "The council has been in discussions with the school to arrange alternative teaching accommodation and the priority is to re-open the school as quickly as possible.

"We have to protect the health and safety of all pupils and staff, and it has been decided to delay the school's opening for one week, to allow time for the installation and preparation of the new temporary classrooms."
