Police have carried out more searches at Peterborough Railway Station in an attempt to stop drugs being brought into the city.
Officers from Cambridgeshire police and British Transport Police were at the station today.
A metal detector was placed in the foyer at the station, and sniffer dogs were also used.
Body language experts were also on hand to spot people acting suspiciously.
Three people were arrested as part of the operation. One was arrested for possession of cocaine and another for possession of cannabis. They were both dealt with at the scene.
An 18-year-old man was arrested on suspicion of possession with intent to supply cannabis. He has been taken to Thorpe Wood Police Station.
The day was part of a week long operation to tackle ‘county lines’ drug dealers, who bring the illicit substances into the city from London and other major cities.
A similar operation was also held at the station earlier this week.
