The real reasons behind a huge police operation in Honley have been revealed.
A gun and ammunition was seized after police acted on a tip-off.
Drugs were also found and inquiries are continuing.
More than a dozen armed police officers swooped on a property in Honley last month in a pre-planned operation.
Seven to eight cars and vans filled with officers, many of them dressed in black and wearing masks, were called to a property in Woodhead Road, along with a dog unit, shortly after 7am on March 31.
At the time police said it was an “intelligence-led operation” and would only confirm that a small amount of cannabis had been found.
It is believed the drugs were being grown in a caravan parked up off the road.

But today a spokeswoman for West Yorkshire Police said: “Police in Kirklees are encouraging residents to report any suspicious activity to them after information from the public helped lead to the discovery of cannabis plants and a firearm at a property in Honley.
“A firearms warrant was executed at an address in Woodhead Road, Honley, on March 31.
“Searches were made of the premises and a number of caravans on site, with 48 cannabis plants found and a shotgun and live cartridges seized.”
Det Insp George Bardell, of Kirklees District CID, said: “Our enquiries continue into the drugs, firearm and ammunition found at this property in Honley.
“I hope the action we have taken serves as a timely reminder to members of the public that we will act on information provided to us about potential criminality in our communities.
