Steven Lyons is the current head of the Lyons clan, which was originally based in the north of Glasgow and latterly in Cumbernauld, North Lanarkshire.
It has been involved in a bloody feud with the rival Glasgow-based Daniel gang for more than 20 years.
It was reported earlier this month that Lyons had been arrested in Bahrain – five months after being released from custody in Dubai.
But in the weeks that followed, details of his whereabouts were shrouded in mystery – until he stepped off a flight in Bali.
In a statement, the Ngurah Rai Immigration Office said: “Based on intelligence data, SL is strongly suspected of being the leader of an international criminal organisation.
“He is suspected of being the mastermind behind the operation of several fictitious companies and of being involved in money laundering.”
Steven Lyons is currently being held at the Bali airport’s detention centre.
