AN ARSON attack has badly damaged a doctor's surgery and shut a supermarket.
The blaze started at around 8.20pm last night and swept through a large part of the Crosland Moor Health Centre on Park Road West.
The next door Co-op store was badly damaged. Both buildings were closed today.
Police confirmed this morning they have arrested a 17-year-old Crosland Moor youth in connection with the fire.
Doctors have set up a temporary surgery in the Crosland Moor Community centre next door for 4,600 patients.
The fire is thought to have started when a trolley full of cardboard was set alight at the rear of the supermarket.
Co-op assistant manager Alison Gannon said a small fire had been found and extinguished near the delivery entrance, where there was a stack of cardboard.
But five minutes later, staff found more cardboard had been set alight and this fire had spread to the roof.
The Co-op and surgery have a joined roof and the flames had spread under the slates.
The fire badly damaged the Co-op's roof void and also hit power supplies to the chiller cabinets and freezers.
Miss Gannon said: "We will have lost a lot of money in stock.
" It is a shame for customers, especially elderly people. The roof should be fixed today and we are hoping to open tomorrow."
Damage was more severe at the surgery.
Rooms - including two consulting rooms - were gutted and the roof had caved in.
Doctors Michael Taylor and Vivien Martin were seeing patients today from a makeshift base at neighbouring Crosland Moor Community Centre.
Senior partner Dr Taylor said: "It is a complete mess. This attack is a bad one.
We have no phones, no computers and no premises."
Patients cannot make contact the surgery by the usual phone number but Dr Taylor urged people in need of treatment to contact the NHS Direct phoneline on 0845 46 47 and they would contact the surgery.
A receptionist has also been sent to St Luke's Hospital in Crosland Moor to deal with patient queries on 01484 466000.
Kath Basnett, director of patient experience at Huddersfield Central Primary Care Trust, said: "The practice has computerised records and a back-up file was stored in a fire-proof cabinet, so none of the patients' information has been lost.
"Anyone with an urgent condition is being seen in the Community Centre and patients with non-urgent complaints are being asked to return at a later date.
"The practice hopes to have its usual surgery telephone number connected to the community centre by the end of today.."
Station officer David Rawnsley, of Huddersfield fire station, said: "When we arrived, my experience told me the flames had got under the eaves and into the roof void so it would be difficult to put out.
"The only way to do it is to strip the tiles from the roof."
He requested back-up from Slaithwaite, Brighouse and Elland. At its height the blaze was being tackled by 23 firefighters.
