Three hand grenades were among a stockpile of weapons and drugs seized by Red Deer RCMP on June 27, police said Friday.

Body armour, seven firearms and ammunition were also recovered by Mounties following a 10-day drug trafficking investigation in Red Deer and Sylvan Lake.

Just over 400 grams of methamphetamine was seized, as well as small quantities of fentanyl and cocaine and about $25,500 cash.

Military members at CFB Wainwright have since taken possession of the grenades.

Three people are collectively facing 35 charges related to the bust.
