Cannabis worth £100,000 and five firearms were seized in a crackdown on drugs and organised crime in Doncaster.
Officers carried out a series of early morning raids in Thorne on Friday and made five arrests.
South Yorkshire Police said officers raided a number of properties on land just off Gibbons Lane using search warrants obtained under the Misuse of Drugs Act.
Around 100 officers were involved in the operation, which was aimed at disrupting organised crime.
In addition to the five air guns, officers also seized a number of other weapons, including a machete.
Over £3,000 was seized along with two dogs, a stolen car and a number of mobile phones.
Doncaster District Commander, Chief Superintendent Shaun Morley, said: “The recovery of £100,000 of drugs and weapons is the most recent success in our proactive approach that has significantly reduced and disrupted drug supply networks in the Doncaster area.
“We have completed approximately 100 similar operations over the last 12 months and arrested numerous people involved in organised criminality.
“Drug supply and organised criminality negatively impacts on all our communities and we will relentlessly pursue those that choose to involve themselves in this destructive lifestyle.”
