A 9NEWS reporter has been pelted with eggs outside a Sydney home raided by counter-terrorism police today.

Two Merrylands men, aged 22 and 24, were arrested this morning during raids linked to the deadly shooting of NSW Police worker Curtis Cheng last week.

Journalist Natalia Cooper was filming a cross in front of the home when a series of eggs were hurled in her direction.

Cooper managed to avoid the projectiles, which were not thrown from the property where the arrested men lived.

It followed an earlier incident when a woman, believed to be a relative of the arrested men, clashed with media as she entered the home.

The woman snatched microphones and threatened reporters before police defused the situation.

Four men and a teenage boy were arrested in co-ordinated raids of four homes this morning.

The operation was linked to the murder of Mr Cheng by 15-year-old high school student Farhad Jabar outside police headquarters on Friday.
