A BOY has been charged with manslaughter after a pregnant woman was killed in a high-speed crash with a stolen car in Hobart, police say.

The 15-year-old, who cannot be identified for legal reasons, was also been charged with motor vehicle stealing, police said.

He was expected to appear in the Hobart Magistrates Court later today.

A 32-week-term baby was delivered alive from the woman who died in the collision about 1am today in central Hobart.

“At this stage the baby is alive,” Tasmania Police Commander Glenn Frame told reporters this morning.

“Our deepest sympathy and condolences go out to the family and the friends of the deceased.

“It was an avoidable tragedy.”

MyState financial group has established a fund for donations to the family of the woman who was killed.

Donations can be made at any MyState branch or by transferring to BSB 807-009, account number 60207105, and account name MyState.

EARLIER: A manhunt was underway for the driver of the stolen car, while three youths travelling in that car, a Toyota Rav, escaped the crash with minor injuries.

They were two girls aged 12 and 15 and a boy aged 15.

The alleged driver, 15, was later this morning located at a house in Kingston and treated for minor injuries.

The woman, 24, died as a result of the crash and her unborn child was later delivered at the Royal Hobart Hospital, police said.

Police said her two-year-old son was also in the car and received only minor injuries.

The woman was returning home after dropping her partner to work at a bakery.

Police first spotted the stolen car on Hobart’s Eastern Shore about five minutes before the crash.

It was later seen travelling about 120km/h over the Tasman Bridge, police said.

Officers had tried to intercept the car but did not engage in a pursuit for safety reasons, Commander Frame said.

A police statement said: “Based on information received, police believe the stolen Toyota Rav (Qld registration 13 LUK) contained four occupants at the time of the crash, all youths.”

”The driver decamped the scene, immediately following the crash.”

The collision happened at the intersection of Davey and Argyle streets, regulated by traffic lights.

There were no obvious signs of braking visible at the crash site.

Wreckage was strewn across Davey St this morning, with the badly damaged Toyota Rav and a sedan on opposite sides of the wide arterial road just behind the Hobart Town Hall.

The Toyota Rav had come to a stop 15 metres further up Davey St after smashing into the Maritime Museum of Tasmania property.

The sedan came to a stop five metres further up Davey St on a footpath near the Tasmanian Travel and Information Centre.
