A woman has handed herself in to Lake Illawarra Police Station on Sunday afternoon following inquiries into the fatal crash at Albion Park Rail in May.
The 25-year-old woman is alleged to have been involved in a collision that killed 25-year-old Daniel Merrett in the early hours of May 18.
The crash also left three others with serious injuries when a Ford Territory struck a petrol tanker at Albion Park Rail.
About 4.40pm Sunday the woman attended Lake Illawarra Police Station where she was arrested and charged with robbery while armed with a dangerous weapon.
She was refused bail and will appear in Wollongong Local Court on Monday.
Two men are also before the courts relating to the crash.
