A 53-year-old male has been charged with drug-related offences and imitation firearm.

A 40-year-old man has been charged with drug-related offences.

They were both granted bail and will appear in Dandenong Magistrates' Court on 15 May.

A 40-year-old man was released on a summons for a possessing cannabis charge, while a 37-year-old male was issued with a drug diversion.

A 54-year-old man was arrested at the property and released without charge.

The arrests were made as part of an investigation into an alleged heroin trafficking ring in Greater Dandenong.

Police have arrested 40 people in total, with 25 arrested during a two-day blitz on December 22 in Springvale.

The charges included possession of heroin and methylamphetamine, handling stolen goods and other outstanding warrants.

"We know the use of illicit substances comes hand-in-hand with further crimes being committed in the area, as well as drug overdoses," Springvale Divisional Response Unit Detective Senior Sergeant Jarrod Dwyer said.

"Getting dangerous drugs off the street is of the utmost importance to Victoria Police.

"While there has already been a significant number of arrests relating to the heroin market in Dandenong and Springvale over the past few weeks, we will continue to do everything possible to disrupt the flow of illicit drugs in our local community."

A further 12 were arrested on Monday 1 and Tuesday 2 January, and were charged with a range of offences, including drug-related offences, assaulting a police officer and dangerous driving.
