FIREFIGHTERS in this area have issued a warning to people selling or storing fireworks illegally.
The warning was made to coincide with the run-up to Bonfire Night.
Nick Sutcliffe, station manager at Slaithwaite, Marsden and Meltham fire stations, said firefighters would use the law to punish people responsible for illegal firework sales.
He added: “If we can stamp this out we will.”
The West Yorkshire fire service investigates all complaints of illegal sales.
People convicted of the offence face fines of up to £5,000.
Mr Sutcliffe said: “I would also like to encourage people who know of fireworks being sold illegally to contact us.
“We will go and have a look and then deal with the matter accordingly.’’
The law limits the periods when shops can sell fireworks to the public without a special licence.
These include on the first day of the Chinese New Year and between October 15 and November 10.
Some shops and specialist suppliers have licences to supply fireworks throughout the year.
But they must make these licenses visible to the public.
A West Yorkshire fire service spokesman said illegal suppliers typically sold fireworks at car boot sales, from the backs of vans and from houses.
He added: “We act on all complaints and suspicions.
“This has resulted in a number of successful prosecutions in recent years.
