An accused accessory to the murder of Leeton schoolteacher Stephanie Scott did not apply for bail in a last-minute appearance at Sydney’s Central Local Court on Thursday.

Marcus Stanford, 24, faced the court after his extradition from South Australia.

Stanford was arrested in Forreston, South Australia, on Wednesday morning, and is accused of helping his identical twin brother, Vincent Stanford, cover up the crime.

He was extradited to New South Wales on Thursday, boarding a Qantas flight from Adelaide flanked by four police officers.

He arrived at Sydney Airport just before 12:00pm (AEST) and was escorted to a waiting car by police and taken to Sydney Police Centre.

His arrest comes after Marcus’s twin brother, Vincent Stanford, was charged with murdering and sexually assaulting Ms Scott in the NSW Riverina town of Leeton in April.

Police allege Vincent sent items belonging to Ms Scott in the post to Marcus, who then disposed of them, after Ms Scott’s death.

Facing the magistrate in South Australia on Wednesday, he was asked if there was any reason why he should not return to Leeton in New South Wales.

“I’ve never been there so I wouldn’t need to return,” he said.

The 26-year-old English and drama teacher was last seen alive at Leeton High School about 11:00am on Easter Sunday – just days before her wedding.

Vincent Stanford was arrested and charged with her murder four days after her disappearance.

The next day, on April 10, Ms Scott’s burnt body was found by police in the Cocoparra National Park about 70 kilometres from the town of Leeton.
