Drugs with a street value of £40,000 have been seized in a crime crackdown across the north east of Sheffield.
Police - some working undercover - arrested 26 people in two days as part of the blitz which has been codenamed Operation Kasna.
Electrical equipment and jewellery worth a total of £20,000 was recovered from the homes of known offenders, as were two stolen vehicles together worth £30,000.
Six warrants have been executed as part of the operation, including one in the Marcliffe Road area of Hillsborough at 4am on Wednesday.
Several police cars and a police helicopter attended the scene.
The four-week operation, led by the Sheffield North East Police Team, began on Monday focusing on burglary, robbery and vehicle crime.
It aims to reduce crime, bring more offenders to justice, and prevent re-offending.
Safer Neighbourhood Acting Inspector Craig Charlesworth said: “We are providing extra resources in tackling crime and anti-social behaviour in the area.
“We want people to feel safe in their communities and robust action will be taken against anyone caught involved in criminal matters or anti-social behaviour.
“We would like to appeal for anyone with information about these types of crimes, or anyone who has been approached by individuals trying to sell stolen goods, to contact police on 101.”
DS Shaf Rehman, the lead officer for the operation, added: “In the last 48 hours officers in uniform and plain clothes have arrested a number of prolific offenders, some of whom have been charged and have appeared before the court.
“These arrests will continue over the next month and towards the end of the year.”
A 33-year-old man and a 17-year-old man have been charged with burglary, and a further two men have been cautioned for vehicle crime offences.
