Up to 50 firefighters battled a huge industrial fire last night, believed to have been started deliberately with fireworks.

Crews were called to a two-storey building in Nursery Lane, Forest Gate, at about 8pm and spent four hours fighting the flames.

Two men and a woman had escaped the building by the time they arrived while another woman had to be helped to safety.

The cause of the blaze, which caused 50 per cent damage to the ground floor and the roof, is currently unknown although it is thought to have been the result of a fireworks-related arson.

Charlie Pugsley, head of the London Fire Brigade’s fire investigation team, said: “This incident shows just how dangerous fireworks can be and why it is essential that you should always follow the firework safety code.

“With Bonfire Night just days away, we recommend that you go to an organised firework display rather than setting off fireworks at home.

“Fireworks are explosives and can be extremely dangerous and it is just fortunate nobody was hurt in this incident.”

Crews from Plaistow, Stratford, East Ham, Poplar, Leyton and Leytonstone fires stations attended.

No-one was injured and no-one has been arrested although police are treating the fire as “possibly suspicious”.
