Knives hunt at Evans Head
Officers were called to Ocean Drive at 9am by residents who had been threatened by the man.
They described him as being of slight build and of Aboriginal appearance. People told the police he was not wearing a shirt at the time of the incident so they could see he had a large tattoo on his back.
Richmond Local Area Command duty officer Inspector Scott Bingham said officers spent several hours patrolling Chinaman's Beach, the shopping centre and back streets throughout the town but could find no evidence of the man.
Later in the day a member of the public handed in a knife to the police station.
It had been found in a park on the southern side of the Evans River.
Insp. Bingham said police were concerned for the man's wellbeing. Anyone with information should phone Evans Head police on 6682 4202.
