Man arrested over French student's death

The man wanted for questioning over the brutal murder of French student Sophie Collombet has been arrested.

Benjamin James Milward, 25, was taken into custody in the northern NSW town of Coffs Harbour on Monday afternoon and Queensland police are expected to seek extradition on Tuesday.

Ms Collombet's naked and battered body was found by an early morning jogger in a park on the banks of the Brisbane River two Fridays ago.

The 21-year-old Griffith University business student was on her way home after a night class when she was attacked.

While police haven't named Mr Milward as a suspect, he is a "person of interest".

The itinerant was known to frequent the South Brisbane park where Ms Collombet died and was captured by CCTV on the night of the attack.

His aunty Tere Douglas is desperate to hear from him.

"You've got a family here who will support you all the way," Ms Douglas told Network 10.

"We're not going to let you be out there by yourself.

"But you haven't been guilty of anything yet Ben, and we need to sort that out."

Mr Milward is due to appear in the Coffs Harbour Magistrates Court on Tuesday.
