Vehicles travelling to scrapyards in Sheffield were stopped by police in a crackdown on metal theft across the city.
Officers pulled over vehicles at checkpoints at Halfway and Attercliffe to check whether any were carrying stolen goods.
A total of 182 vehicles were stopped and nine scrap dealers visited.
Nine fixed penalty tickets were issued for traffic offences and three vehicles were seized.
Inspector Jason Booth, from Woodhouse and Mosborough Safer Neighbourhood Teams, said: “This was a partnership operation to tackle a problem many people in Sheffield feel quite strongly about.
“We are determined to keep looking at initiatives to stop those who feel that stealing metal is an easy crime and we accept this will take time, but we remain determined in our efforts.”
Chief Inspector Iain Chorlton, responsible for overseeing the police response to metal theft in Sheffield, said: “This kind of operation is an excellent example of partners working together to address the serious issue of metal thefts.
“I would urge anyone with any information about this type of crime to report it to the police.”
The crackdown comes as new figures reveal metal thefts in Sheffield have gone up by almost 50 per cent, with 1,893 offences reports to police in the city over the last year.
Police were informed of the thefts between September last year and the end of August this year - a 46 per cent hike on the year before.
