On Friday morning, the tasking teams in Sheffield and Barnsley worked together to conduct a joint operation following a number of burglaries in which cars were stolen.
Two addresses in the Shiregreen area were searched and a 36-year-old man has been arrested on suspicion of four counts of burglary. The man currently remains in police custody as enquiries continue.
Detective Chief Inspector Paul Wilson, district crime manager for Sheffield and head of the Sheffield Tasking Teams, said: “This week’s activity is a snapshot of the relentless work that the district undertakes day in day out to keep our city safe.
“Clearly the public’s help and support is vital to this work and I would ask anyone with information or concerns about the possible supply of drugs or use of weapons across Sheffield to call 101 or Crimestoppers anonymously on 0800 555111.”
