An Indian mobster caught in Bali after two decades on the run lived in hiding in Australia for seven years and before that in Zimbabwe, police say.
But the man they believe is Rajendra Sadashiv Nikalje - better known as Mumbai gangster Chhota Rajan - is denying his identity.
Nikalje's luck ran out when he arrived in Bali on Sunday, where authorities were waiting after a tip-off from Interpol in Canberra.
The 55-year-old is wanted in India for up to 20 murders, as well as weapons and organised crime offences.
Bali provincial police spokesman Herry Wiyanto told reporters he entered Indonesia on a Sydney-issued Indian passport.
It had the number contained in the Interpol "red notice", but with the name Mohan Kumar.
"Because his passport number is in the red notice and from his face, we believe he's Rajendra," he told reporters on Tuesday.
"We suspect he forged his name in order for him to hide and this is what we are investigating."
Denpasar district detective chief Reinhard Habonaran Nainggolan says Australian authorities were aware Nikalje was living there for seven years.
"He's still not admitting that he's Rajendra, he's still saying he's Mohan Kumar," he said.
"Before he entered Australia, he was in Zimbabwe for several years."
Police were working with Indian authorities on plans to deport him.
In July, The Times of India reported Nikalje was in Australia, in hiding from his underworld rival Chhota Shakeel, an aide of one of the world's most wanted men, Dawood Ibrahim.
Ibrahim, who is said to have close links to al-Qaeda, is wanted for co-ordinating the 1993 Bombay bombings that killed more than 350 people.
