Man accused of car attack appears in court

A Queensland man accused of a knife attack that caused a young mother to suffer a heart attack had his case adjourned in court.

Graham Michael Hughes, 22, allegedly stabbed the side of the car of a 21-year-old woman as she drove with her partner and two young boys at Rainbow Beach on Tuesday.

She remains in a coma at Royal Brisbane and Women's Hospital.

Hughes was refused bail on Thursday and will re-appear in Gympie Magistrates Court on July 4.
