Child threatened with knife in NSW

A 10-year-old girl was grabbed by a man and threatened with a knife as she stood at an intersection on the NSW Central Coast.

The man grabbed the girl and showed her a knife in his jacket, but the girl pushed the man's hand away and ran to a nearby friend's house.

The incident happened at the intersection of Leichhardt Street and Gascoigne Road at Gorokan about 8.30am (AEST) on Wednesday, police said.

The offender is described as 173cm tall, clean-shaven, about 30 years old with a slim to muscular build.

He was wearing black shoes, pants and a t-shirt under a black zip-up hoodie with sun glasses.
