A 65 year old Adamstown Heights man has been held at knife point in a storm water drain at the Kotara Homemaker Centre.

The man was walking home yesterday at about 5pm when 2 men approached him from behind and demanded he hand over his wallet.

One attacker brandished a knife and took the man’s back pack and mobile phone, before the pair fled on foot down the drain toward Newcastle.

They have been described as in their early 20s, of medium build and height, wearing blue jeans and open face balaclavas.

Any witnesses are being urged to contact Crime Stoppers on 1800 333 000.
