THREE people have been arrested on suspicion of conspiracy to commit burglary.
Roads policing officers conducting routine patrols on August 19 on the Barnsley-Wakefield border stopped a white Seat Ibiza on the A638, which connects Brierley to West Yorkshire.
One occupant made off from the vehicle, while the other three were arrested.
Officers searching the vehicle recovered items including a cap with the word ‘police’ on it, protective body armour and a lock knife.
A quantity of cannabis was also found.
Three males aged 17 and two who are 24 remain in custody.
Detective Inspector Heather Shearer said: “The items found within this vehicle are of clear concern we have enquiries ongoing to establish any potential linked offences.
“It also serves as a timely reminder that legitimate police officers will always carry identification.
“If you have any concerns about someone purporting to be the police you can ask them to verify their identity and, if you continue to have concerns, should call 101 or 999 in an emergency.”
