A convoy of police vehicles, including the armoured Bearcat truck, descended on Albert Road at Auburn on Monday afternoon with the focus on a multi-level family home.

Heavily-armed police piled out of the truck and used a megaphone to tell the resident inside to come out with his hands above his head.

Within minutes, Ahmad Abdullah emerged and was handcuffed and placed on his knees on the ground.

Police allege Mr Abdullah, 25, robbed a man of $300 in Guildford on January 10 before going to his home and extorting the man further.

It is alleged the victim had carried out work on the Abdullah home and a dispute stemmed from that.

Mr Abdullah was also the subject of an outstanding arrest warrant for the alleged extortion of a man with cerebral palsy in September, 2013.

It is alleged Mr Abdullah and two others extorted $15,000 cash from the man, who lived in Greystaynes.

Mr Abdullah's brother Mohammad Abdullah, 23, who was arrested at Auburn Police Station on Monday afternoon, has been charged with demand property in company in relation to the January 10 extortion.

At one point Ahmad Abdullah began yelling as police surrounded his home on Monday and Tactical Operations Unit police led him to the other side of the road and made him lay on the footpath.

Two women and children also emerged from the house and sat on the back of the police truck.

The operation played out in full view of a childcare centre across the road.

Many parents were anxiously waiting at the road block at the end of the street for the road to reopen so they could collect their children.

Neighbours say the police have visited the seven-bedroom home, which is currently on the market for $1.5 million, before.

Mr Abdullah was laid with five charges overnight, including take and detain in company with intent to get advantage.

Mohammad Abdullah was charged with demand property in company.

The brothers are due to appear in Burwood Local Court on Tuesday.
