Accused robber surrenders after 17-hour stand-off on TAFE rooftop

A 27-year-old man wanted over a triple-stabbing and two armed robberies is in police custody following the end of a 17-hour siege.

NSW Police wanted to question the shirtless man over a triple stabbing and two armed robberies, but weren’t able to coax the man down.

As a precaution, police blocked off Henry Street in Tighes Hill and asked people to avoid the area.

Three gym mates were stabbed at a gym in Brookvale in Sydney's north.

Police believe the man in the rooftop standoff is responsible for two armed robberies at Newcastle service stations on Monday night, and is the same man who stabbed three people in Brookvale on Sydney's northern beaches.

Police said an "agitated and aggressive" man entered a gym on Pittwater Road at 8pm Monday night.

The gym mates, Nicholas Worsley, Daniel Fernandez and David Burns, were stabbed at the gym.

He allegedly approached four men before punching one and stabbing the other three.

One of the stabbing victims, Nick Worsley, was stabbed five times and bleeding badly as he stumbled to a nearby caryard.

He was trying to hide, not knowing if his attacker was close behind.

His friends Dave Burns and Dan Fernandez headed in different directions both just wanting to get to safety, one stumbling to a neighbouring home.

"I just heard a gentleman yelling out the front of the house, yelling for help, help," an unidentified witness said.

"I opened the door noticed that this guy was bleeding quite bad, holding his neck."

The three stabbing victims were taken to Royal North Shore Hospital with one man undergoing immediate emergency surgery while the other two were reportedly in a stable condition.

Around the same time the alleged attacker then ran to a stolen vehicle and fled the scene.

That stolen black BMW belongs to Bill Pulver, the boss of Australian Rugby Union and the father of Maddie Pulver who was the victim of the collar-bomb siege in 2011.

Police say the man then drove 170 kilometres to Newcastle where he robbed two service stations armed with a knife.

The first robbery occurred about 9.45pm on Maitland Road in Sandgate when a male driver pulled into petrol bowsers and started filling his vehicle.

The 38-year-old female service station worker thought the driver appeared suspicious and approached him, only to have him follow her into the shop all walk behind the counter area.

He then started threatening to smash the cash register before pulling a knife on the woman, police said in a release.

He fled the scene with an amount of cash.

Police believe the same man showed up 15 minutes later at another service station on Maitland Road and placed two chocolates on the counter.

When the 24-year-old woman behind the counter opened the till, the man jumped the barrier.

He pulled a knife and took an amount of cash before fleeing in the car.

Police tried to intercept the stolen vehicle but it managed to evade pursing officers.

No one was injured in the robberies, police said, but CCTV from one of the service stations shows the man battering at the register.

He jumps and kicks at the till draw several times before ripping the whole thing from the counter and taking off with it.
