Fire crews are tackling another blaze at the old Pontins site in Hemsby.

Six fire crews were called to the site at 1.20am this morning when a passerby reported seeing flames.

One crew is still on site and day crews will be returning later this morning to fight the flames.

Norfolk Fire and Rescue Service is advising people nearby to stay inside and keep windows and doors closed.

The fire is believed to have started in the old theatre in the main building.

Five pumps and an aerial ladder platform have been used to beat flames.

In the last five years Norfolk Fire and Rescue Service have been called to the former camp 15 times.

The most serious incident was in August last year when 90 firefighters battled a blaze at the main clubhouse of the 2,440-capacity park.

Some firefighters remained on the site for several days.

A single, basic call-out for the fire service costs around £300, meaning the total cost to the taxpayer is likely to run into thousands.

James Bensly, a borough councillor, has previously said the owners Northern Trust should be made to pay for the emergency response.

Last month Great Yarmouth Borough Council approved controversial plans to build nearly 200 homes on the site.

Objections had been lodged by residents, Hemsby Parish Council and Great Yarmouth MP Brandon Lewis - all adamant the land should be retained for holiday use.
