The man behind the wheel of a stolen black Audi at the centre of a police pursuit that left a Sydney toddler dead has been on the run since dumping his car at Darlinghurst last night, but police are drawing the net tighter.

An image has been released of Christopher Chandler, the man believed to have been driving the car which smashed through the fences of a residence in Constitution Hill in Sydney's west, and a warrant issued for his arrest.

He is wanted in relation to the theft of a charcoal-coloured Audi A4 sedan, but he would likely face other charges relating to the tragic pursuit when arrested.

The car was found abandoned just after 7.30pm on Bourke Street, near the intersection with Forbes Street in Darlinghurst.

Chandler, 22, is described as being of Caucasian appearance, with a fair complexion, short brown hair, facial hair, green/hazel eyes, about 175-185cm tall and of a thin build.

Meanwhile, the community is in mourning after a toddler was killed in a tragic end to a police pursuit.

People watched in horror yesterday as 17-month-old Tateolena Tauaifaga was fatally knocked down by vehicles engaged in a chase in Constitution Hill in Sydney’s west.

Police pursued a suspected robber in a black Audi to a quiet suburban cul de sac where children and families were enjoying the summer day.

The pursuit was called off seconds after Tateolena was struck.

Two of her siblings were also hit, but survived.

Uncle Tulaga Toleafoa said there was some blame being directed towards the officers, some of whom were seen cradling their heads in the aftermath.

“They blame the police and the way they handled it,” he said.

“But then again they were doing their job.”

Family, friends and neighbours laid flowers at the site.

The pursuit took place after investigators working to solve a spate of robberies in Constitution Hill rolled in to Bessbrook Way in an attempt to corner a stolen black Audi with a suspect inside.

Six police vehicles closed in but the Audi sped away towards the young children playing nearby, smashing through a back fence and the driver fled.

The car was later found abandoned in Kings Cross.

Assistant Police Commissioner Frank Minelli offered his sympathy to the grieving family.

“My condolences goes to the family and friends of that child, it is a pain that no parent should go through,” he said.

An independent team of officers is now investigating the incident to determine whether the toddler was struck by the suspect or a police vehicle.

The suspect’s alleged passenger, 22-year-old Katie Tuite, was arrested this morning in Darlinghurst.
