The Australian Federal Police will not say whether they are investigating claims the father of convicted drug smuggler Schapelle Corby owned the marijuana that led to her 20-year Bali jail sentence.
Corby's sister Mercedes has called for the police to disprove allegations from convicted drug trafficker, Malcolm McCauley, that he supplied the late Michael Corby with the drugs.
Mr McCauley also told Fairfax newspapers that Schapelle knew how the drug smuggling operation worked.
Schapelle Corby is serving a 20-year jail term in Bali's Kerobokan prison after being convicted in 2005 for smuggling 4.2kg of marijuana in a boogie board bag into Denpasar airport.
Mr McCauley said the plan "broke down on the day" because a series of $1,000 bribes also placed in the bag went missing before the bag went through airport security.
