Just after midnight on July 21), a 46-year-old man answered a knock at the front door of his Petra Avenue home and was confronted by a man armed with a knife.

It is alleged the armed man threatened the 46-year-old and forced his way inside, with three people following him.

The 46-year-old’s son, aged 26, was inside and ran out the back door where four people, waiting at the rear of the home, assaulted him.

When the 46-year-old man ran to assist his son, he was allegedly stabbed in the lower back.

The group stole the man’s wallet and prescription drugs before leaving in an older-model white Commodore sedan.

Police and Ambulance paramedics were called and the 46-year-old man was taken to Tamworth Hospital with non-life threatening injuries.

Police have released images of two men who may be able to assist with inquiries.

The first man is about 30 years of age, has a solid build, approximately 177cm tall, with brown eyes and a receding hair line.

The second man is about 20 years of age, approximately 175cm tall, and has a small to medium build.

Both men are heavily tattooed.

Anyone with information on the men is urged to contact Tamworth police or Crime Stoppers.
