A violent argument over a car space in one of Sydney's busiest shopping malls has left one man fighting for life after he was stabbed in the back and stomach.

Jerry Uesele, 39, was last night in a serious condition in Liverpool Hospital after the stabbing on Thursday during a fight over a car space in Fairfield's Neeta City Shopping Centre.

Horrified shoppers watched on as Uesele was stabbed three times in the back and stomach about 11:30 a.m.

The man who allegedly attacked him — Robert Silvester Gregorec — was apprehended by mall security guards and held until police arrived.

Gregorec, 32, of Villawood faced Fairfield Local Court Friday charged with maliciously inflicting grievous bodily harm. He did not enter a plea or apply for bail.

It is understood witnesses have told police the victim was sitting in his car in the multi-story car park at the Neeta City Shopping Centre when he was approached by Gregorec, who was waiting to take his space.

A verbal exchange followed in which Gregorec allegedly told Uesele to hurry up and leave the space so he could have it.

The altercation allegedly turned violent when Gregorec returned to his vehicle and got a knife and returned to Uesele's car.
