TWO men have been charged with serious drug offences after more than two kilograms of methylamphetamine and approximately $50,000 in cash was seized.

On Tuesday, October 22, officers conducted a Border Search Area at Perth Airport targeting passengers arriving on domestic flights from Sydney and Melbourne.

Intelligence led officers to a 76-year-old man who arrived on a flight from Melbourne who was believed to have had a quantity of drugs in his possession.

The male was observed at the airport by officers before he left during the search and later returned to collect a bag.

Officers followed the man to an address in Dayton, where a traffic stop was conducted and the 76-year-old male and a 55-year-old male were taken into custody.

It will be alleged the bag that was collected at the airport by the 76-year-old male contained more than two kilograms of methylamphetamine.

A subsequent search of the home in Dayton located more than $50,000 in cash which it will be alleged is the proceeds of drug offences.

The 55-year-old male from Dayton has been charged with possession of a trafficable quantity of methylamphetamine with intent to sell or supply, one count of received, possessed, concealed, disposed of or dealt with any money or other property that is the proceeds of an offence and supplying a prohibited drug.

He is next due to appear before the Perth Magistrates Court on December 5.

The 76-year-old male from Balga has been charged with one count of possession of a trafficable quantity of methylamphetamine with intent to sell or supply.

He is due to appear in the Perth Magistrates Court on November 7.
