EXTRA police will be on patrol to catch youngsters causing trouble around Bonfire Night.
Around 20 extra officers - boosted by specials and new community support officers - will be on the streets of Huddersfield on November 4 and 5 to deal with problems caused by children.
And police have also warned children caught causing criminal damage face being arrested and prosecuted.
Insp Mark Broadhead, of Huddersfield police, said: "A lot of things that happen on so- called Mischief Night on November 4 are not high jinks. It is criminal behaviour and will not be tolerated."
He revealed that every community constable in Huddersfield along with community support officers and special constables will be on patrol on the evenings of November 4 and 5.
Shopkeepers have already been warned they face prosecution if they are caught selling fireworks to youngsters aged under 18. Trading standards officers will be going to shops undercover to do tests buys to make sure the law is not being broken.
Shops have a voluntary agreement with the police not to sell fireworks until three weeks before Bonfire Night and a week after.
A purge is on to catch people selling imported fireworks.
One Huddersfield man has already been arrested for doing this and a large quantity of fireworks were seized.
Insp Broadhead said: "Clearly fireworks are potentially very dangerous if they are let off in streets and powerful fireworks imported illegally from abroad can be particularly dangerous."
He also urged parents to make sure they know what their children are doing in the week around Bonfire Night.
He said: "If fireworks are being let off they could get hurt, or they may be held responsible for injuring others."
