Three men arrested during a series of raids in Sheffield have been released on bail.
Officers from South Yorkshire Police carried out raids at six properties across the city on Monday – the first day of a six-week operation to crack down on burglary and stolen goods.
More than 50 officers working in teams targeted addresses in Aughton Crescent, Danewood Avenue and Danesbrook Close, all in Manor, Heeley Bank Road in Heeley and Kyle Close and Deerlands Avenue in Parson Cross.
During their searches they discovered a handgun, a suspected stolen laptop and a haul of suspected stolen mobile phones.
One man was arrested on suspicion of possessing a firearm and two other men were arrested on suspicion of handling stolen goods.
A South Yorkshire Police spokesman said: “All three men arrested have been bailed pending further enquiries.”
Operation Kustody will continue for the next six weeks with officers targeting suspects and carrying out further crime prevention initiatives.
Superintendent Scott Green said: “Reducing burglary is a key priority for the force.
“It can have a huge impact on victims and is a crime we are determined to tackle.
“Clamping down on the stolen goods market is one of the most effective ways to do that; if burglars can’t sell on what they’ve stolen it makes the crime less attractive a prospect.”
