A man has been charged after allegedly leading police on a pursuit through Sydney's west that ended in a two-hour siege at an apartment block.

The chase began just after 3am when police tried to stop a Toyota Camry on Aurora Drive in Tregear.

Police began chasing the car along Luxford Road, where it was allegedly seen on video speeding, before it turned into a block of flats on Halinda Street in Whalan.

Police allege Shaun Baxter, 38, got out of the car and went inside, leaving a passenger behind.

Police arrested the passenger but said he was quickly released after they spoke to him.

They set up a perimeter around the apartments, waiting for the man to come out.

Police told residents to stay inside for their own safety.

"[A] swarm of cops followed after, [the] canine unit and more cops came up, got a scent of him, took off down the driveway," witness Declan Boulson said.

When Baxter emerged at 5am, he was arrested and charged with multiple offences.

That includes not stopping leading to a police pursuit, driving recklessly, dishonestly obtaining financial advantage by deception, and breaching a domestic violence apprehended violence order.

He appeared in court today, where he was refused bail.
