A key suspect in the kidnapping and murder of former Hells Angel bikie and underworld figure Wayne Schneider in Thailand has turned himself in. 
Sources have told Fairfax Media Sydney man Antonio Bagnato, 26, was detained in Phnom Penh after handing himself in. He may have since been transferred to Bangkok.
Mr Bagnato is wanted for questioning over the death of Mr Schneider, whose naked body was found in a shallow grave near the Thai tourist city of Pattaya on Monday.
However, it is understood Mr Bagnato is also wanted for questioning over the shooting of Brad Dillon in Sydney last year.
Fairfax Media has been told discussions were going on between Mr Bagnato's lawyers and NSW detectives about bringing Mr Bagnato back to Australia to face allegations relating to Mr Dillon's death.
Mr Bagnato's lawyer, Theo Tsambas, said he was aware his client handed himself in to police in Cambodia.
"I can also confirm that the Australian embassy in Cambodia know about him but have not seen him or don't know where he is," he said on Friday.
"I am told that he was taken back by the AFP to Bangkok. It is my understanding having spoken to family members that he is currently at a police station in Bangkok."
However an AFP spokesperson said they had no involvement in his arrest.
Thai police say they have now identified the five masked gunmen who kidnapped Mr Schneider and buried his naked body with a broken neck in a two-metre grave in woodlands a short drive from his rented home in the Thai tourist city of Pattaya early Monday.
