A missing child was discovered as police swooped on a series of homes during a two-day drugs raid.
Operation Scorpion, launched by South Yorkshire Police to crackdown on dealers in southwest Sheffield, led to seven arrests, including two wanted suspects.
Five people were detained on suspicion of drugs offences.
Officers also unearthed cash and Class A drugs during the raids on 24 and 25 August.
Six vehicles believed to be either stolen or uninsured were also seized.
The crackdown, in the areas of Lowedges, Batemoor and Jordanthorpe, was launched in the wake of a string of violent incidents, the force said.
The missing child, who has not been identified, was found at one of the properties where a warrant was executed.

A statement from South Yorkshire Police said: “Four warrants were executed in the area and 14 stop and searches were carried out.
“This led to seven arrests, five of which were for drugs offences, as well as the recovery of cash and Class A and B drugs, including heroin, crack cocaine, amphetamine and cannabis.
“Six vehicles were also seized for having no insurance or as they were believed to be stolen.
“Of note, officers also located a missing child at an address where a warrant had been executed.”
Police also worked alongside Sheffield City Council to conduct checks to retail outlets, where more than 300 “illegal and dangerous” vaping devices and a haul of illegal alcohol was found.

Acting Detective Inspector Matt Lavender said: “I’m pleased that, as a result of this activity, two wanted individuals were located and drugs, cash and stolen vehicles were recovered and are no longer in the hands of those intent on committing crime.
“By detecting and disrupting criminals and criminal behaviour, and displaying a high visibility police presence, we are able to show the public that we continue to keep the public safe and deny criminals a place in our communities.
“This is particularly important in areas like Lowedges, Batemoor and Jordanthorpe where we know there have been a number of concerning incidents recently, so we want our communities to know we’re acting on their concerns.”
He vowed the force would do “everything within its power” to bring criminals to justice.
