Two people have been arrested following a savage stabbing attack on a 25-year-old woman at a Melbourne shopping centre.
Moonee Ponds detectives arrested a 37-year-old man and a woman in her 20s just after 5.30pm (AEDT) in Sunshine North on Tuesday.
Emergency services were called to an upper level car park at Airport West shopping centre about 9.15am after the woman was stabbed in the head and upper body.
Paramedics found her unconscious and lying in a pool of blood near her car.
Detective Sergeant Michael Engel said the female attacker was known to the victim.
"It's possibly a disgruntled worker or ex-working employee - it certainly wasn't a random attack," Det Sgt Engel said.
He said it was a particularly vicious attack that was launched in front of dozens of shoppers as well as the victim's husband.
The injured woman, who is in an induced coma in a critical condition in the Royal Melbourne Hospital, owns a nail salon at the shopping centre.
Anyone who may have witnessed the assault is urged to call Crime stoppers.
