Officers from the city’s Community Policing Team were on patrol in the Kingsmead Road area on the morning of Wednesday 7 April 2021 when they spotted suspicious activity nearby.
Three men were spoken to before a man was arrested on suspicion of possessing class A drugs with intent to supply.
The 20-year-old has since been released under investigation while enquiries continue.
A quantity of suspected crack cocaine, cash and a mobile phone has been seized as part of the ongoing investigation.
Acting Sergeant Richard Lorimer, of Canterbury Community Policing Team, said: ‘Kent Police is committed to disrupting and shutting down the drug dealing networks which target vulnerable people in our communities and I am pleased that, in this instance, class A drugs and criminal cash have been removed from circulation in Canterbury.
‘I urge anyone who believes drug dealing is taking place in their area to report it to Kent Police on our website, by calling 101, or by dialling 999 if a crime is in progress.’
