Investigators allege he is the mastermind behind a sophisticated crime syndicate which manufactures drugs and traffics them through Melbourne’s south-east.
Police also allegedly found $65,000 in cash, two samurai swords, and equipment used to make drugs at his home.
Two women, both aged in their 50s, were also arrested at the property.
Police raided a total of five buildings at around 9am as part of their move on the syndicate, which they have been investigating for 12 months.
The 55-year-old man will face court tomorrow.
