Drugs worth £8,500 were seized by police during 16 raids carried out in a day of action in Sheffield.
Stolen plant machinery and tools were also found by officers during searches of properties in and around Parson Cross, Burngreave and Fir Vale.
Operation Portable Cullis involved 120 officers and was aimed at tracking down known or suspected criminals.
A total of 14 arrests was made for offences including theft, driving while disqualified, handling stolen goods, breach of bail, possession of cannabis and drink driving.
Officers also seized 14 vehicles where drivers were found without insurance, MOTs or tax or where it is believed vehicles had been used in crimes.
Inspector Glen Suttenwood, leading the operation said: “This operation was intended to reassure communities and target offenders in the north east of Sheffield, and I believe we achieved our objectives.
“We arrested known offenders, recovered stolen property, seized drugs and removed 14 vehicles off the road which should not have been there.
“The areas were chosen because traditionally there is a slight rise in criminal activity in the run-up to the Christmas period in these areas.
“We pulled together a large team of specialist staff with a clear aim of making a positive impact in the area, and I hope the results speak for themselves and the residents in the areas feel more reassured and safer.”
