A man was arrested following a two-hour stand-off in Grafton on September 20.

Shortly after 9am, officers from the Coffs Clarence Police District and emergency services attended a Turf Street residence after concerns were raised for the welfare of an occupant.

It was initially thought a siege was underway.

When police arrived, a 29-year-old man made verbal threats against them while armed with a knife.

Two women and a young boy were evacuated from the property and a perimeter was established while the man remained at the location.

Tactical support was called in while negotiations took place between the man and the police throughout the rest of the morning.

For the next two hours, the man repeatedly went in and out of a shed on the property while speaking and not speaking to the police at different times.

The man was arrested following the arrival of specialist resources just before 12pm and transported to Grafton Police Station by ambulance for questioning.

The man was later conveyed to Coffs Harbour Health Campus for assessment. 

No injuries occurred during the operation.

Investigations are ongoing.
