The bellboy at Legends Hotel who disappeared from Mauritius before he could give evidence at Michaela McAreavey's murder trial has returned to the island to speak with detectives involved in the new probe into her death.
Police were under pressure to speak with Rajiv Bhujun, who was with her husband John McAreavey when he discovered his wife's body in their hotel room on January 10, 2010.
Mr Bhujun could not be found when he was called in May to give evidence against his two work colleagues Sandip Moneea and Avinash Treebhoowoon who were on trial for Michaela's murder.
After the two suspects were acquitted following an eight-week trial, police in Mauritius launched a new investigation into the killing of the 27 year-old school teacher.
Mr Bhujun had been working on a cruise ship when he was informed by family members recently that police were keen to speak to him about what he had seen on the day Michaela was strangled to death.
He arrived back in Mauritius on Monday to make a statement to police.
Although Mr Bhujun provided a statement to police at the time of the murder, they hope he will be able to give them new information that could lead to Michaela's killer or killers.
Mr Bhujun was the first person to arrive at the murder scene when John screamed for help after he found his wife's body. Seconds earlier the bellboy had opened the door of the bedroom for John who did not have a key.
On Monday a lawyer for one of the men acquitted of murder said that Mr Bhujun should be able to provide "material evidence which can assist the inquiry".
