Micheal Manyon, 35, arrived in Panaji on Sunday night from Mumbai, where he was staying after he had fled Goa three days after the 15-year-old girl was allegedly drugged, raped and murdered on the state's popular Anjuna beach.

Goa police had issued a look out notice for Manyon. His deposition is likely to throw more light on the last few hours before Scarlett was murdered as he was among the people who were present in a shack on February 17 mid-night when the teenager walked in.

Her semi-nude body was found on the Anjuna beach early next morning.

"I have taken his deposition and later in the day, he will be produced before police. He will give his deposition in the presence of a sub-divisional magistrate," Vikram Varma, who is advising Scarlett's family on legal matters, said.

Varma will also represent Manyon in this case.

Police have already arrested two people -- Samson D'Souza, a barman, and Placido Carvalho, an alleged drug trader, - for "drugging, raping and murdering" Scarlett.

Manyon is one amongst the witness who saw Samson "sexually abusing" Scarlett behind the shack, Varma alleged.

"He told Samson not to mess up with the girl as she is hardly 15," Varma claimed.

The British national's testimony is also likely to highlight the role of another suspect Murli kumar, who is being questioned by police.

Manyon, in his deposition to the lawyer, has said that Murli was allegedly present at the place and was talking to someone on mobile when Samson was "sexually abusing" Scarlett.

The British national had informed the British High Commission in Mumbai about the sexual assault shortly before Scarlett's mother Fiona Mackeown suspected foul play in the matter, according to Varma, who said Manyon had not left India and was in Mumbai all these days.
