A police investigation into the supply and trafficking of Class A drugs saw about 30 arrests in the Dover area over three days.

The first in a series of warrants was executed in Auden Way on Tuesday, where a man in his 50s and a woman in her 40s were arrested for allegedly possessing quantities of heroin and cocaine.

A door was forced open, allowing the officers to gain entry to the house at about 7am.

Sniffer dogs were also used to search the property for any more hidden stashes.

Rob Price, Assistant Chief Constable and head of local policing in Kent, said: “With any job of that scale there has to be a lot of preparation, checking, planning and observations.

“We have to make sure we have the right people.”

Behind the scenes work to pull off this high scale operation is said to have taken months and is something officers have to get right.

This week’s warrants required the work of about 200 officers from various teams within Kent Police.

“These operations are critical,” he said.

“It is important to reassure the community that we are there to deal with issues that impact their quality of life and safety.”

Mr Price said officers know what arrests will be made before the warrants are executed.

“We assess and review them constantly,” he said.

“We then have the evidence to put forward a charge and put them before he courts.

“We certainly know who we are going to deal with and we are confident it is going to be successful before we get to their doors.”

Knowledge is built up when the public inform officers of incidents.

He said: “We are going to interview a lot of suspects when we come out of the operation.”
