A police crackdown on the trade of secondhand mobile phones in Sheffield has led to arrests and the recovery of stolen property.
Officers from South Yorkshire and West Yorkshire have worked together on the operation.
In Sheffield, eight people were arrested on suspicion of receiving stolen property.
Searches of three shops and two homes led to 12 stolen mobile phones being recovered.
Since August, officers have identified a number of businesses, including market traders and shops, willing to accept stolen goods.
Detective Constable Andrew Shaw, who led the operation, said: “We have seen a rise in phone thefts and are looking at the link between organised offenders crossing force boundaries.
“In the last year, we have worked hard to help businesses operate legally and protect themselves from receiving goods from criminals. Unfortunately, some businesses have sought to carry on their criminal enterprise.
“There will be further action taken against criminal gangs who seek to target Sheffield in the run-up to Christmas.”
