A couple has been arrested after a wild police chase in NSW that lasted hours and allegedly involved multiple gunpoint carjackings.
A 33-year-old man is facing 10 charges and a 31-year-old woman was hit with five offences after they were arrested at Parramatta on Saturday evening.
The pursuit began shortly after 4pm on the Federal Highway near Goulburn on Saturday when police spotted a stolen ute, which pulled away when officers tried to stop it.
Police used road spikes at Marulan, puncturing the ute's front tyre.
The pair then got out and allegedly approached another car and threatened a couple and their baby with a shortened firearm.
Police say they stole the family's SUV and continued along the Hume Highway before crashing at a service station at Sutton Forest.
The couple then allegedly threatened a woman and two teenage girls in a hatchback at the service station and stole that car.
They were again pursued for a short time before police called it off for safety reasons.
The stolen hatchback was allegedly involved in a crash with three cars at Mount Annan in Sydney's southeast about 5.45pm before continuing.
It was tracked by police helicopter and finally stopped about an hour later at Parramatta, where the pair were arrested with the help of the dog squad.
The man faces charges of armed robbery, threatening injury, firearm possession and several driving offences.
The woman was charged with armed robbery, threatening injury and assault.
They were refused bail and are due to appear at Parramatta Local Court on Sunday.
