Methamphetamine, cannabis and cash were seized as police arrested 20 people in the Western Bay of Plenty overnight.

Operation Mantis began over a month ago and resulted in search warrants being executed at 10 addresses in Tauranga and Te Puke suspected of being linked to drug dealing.

20 people have been arrested following drug raids in the WBOP last night.

Detective Senior Sergeant Greg Turner says the 20 people, both men and women, have been arrested for serious offences relating to the dealing, supply and possession of methamphetamine and cannabis.

The ages of those arrested range from 18 to 46.

A total of 60grams of methamphetamine, 25 ounces of cannabis, $5000 in cash and numerous items of stolen property have been recovered.

'Police would like to thank members of the public for information that led to this operation and encourage anyone in the community with information concerning drugs or any other crime to contact the police,” says Greg.

'Some of those arrested will appear in the Tauranga District Court this morning; and others over the coming days.”

People with information about any drug activity are urged to contact their local police station.
