Former AFL coach Mark ‘Bomber’ Thompson had 135 grams of MDMA stashed alongside Cats memorabilia inside a hidden, locked room with coded entry from the bedroom of his Port Melbourne apartment, a court has heard.

The premiership coach, 54, appeared worn in the dock on Tuesday evening as Melbourne Magistrates Court heard details of the seven charges laid against him which included the alleged trafficking of ecstasy and ice, each of which carry maximum jail terms of up to 15 years.

Mr Thompson's “surprise” arrest came after he voluntarily attended a police interview hours earlier, unaware of his pending apprehension.

The illicit drugs, both MDMA and ice with a potential street value of more than $50,000, were detailed to a packed courtroom where police labelled him a flight risk due to his access to sizeable amounts of money and a yacht.
