SUSPECTED arsonists have struck a derelict factory for the second time this month.

Fire crews were called to a blaze at the derelict GWK factory in Blackhorse Road, Letchworth GC, last night (Wednesday).

It is the second time this month, with another suspected arson attack at the site on February 6.

Crews from Letchworth GC and Stevenage tackled the blaze, after being scrambled to the scene just after 7.40pm. They were at the site for more than an hour.

Police were also informed, due to the belief the fire may have been started deliberately.

No one was injured.
