Police warned there was a risk of explosion after a fire that started in a printing press quickly spread to the rest of the 2,500 square metre premises.

As the printing works contained highly flammable liquids, police have cordoned off a nearby road in the industrial zone where the printing works is located. The nearest residential area is Stattena in northern Helsingborg.

Forty firemen from Helsingborg, Landskrona, Bjuv and Höganäs have been called in to fight the fire. A number of ambulances have also been dispatched to the scene but there have so far been no reports of any injuries.

With smoke billowing across the city, a number of concerned residents have made contact with the emergency services.

“Smoke is never healthy but you can protect yourself by staying indoors and closing windows and doors,” said fire chief Lennart Nilsson.

Fire services expect to have brough the blaze fully under control in the early afternoon.
