A man remains hospitalised in intensive care after an aggravated break and enter in the state’s north.

About 8.50pm yesterday (Friday 8 March 2013), a 52-year-old man answered a knock at the door of his unit, located above a shop on Fry Street, Grafton.

Police have been told four unknown males forced their way inside and assaulted him.

The 52-year-old was stabbed several times with a sharp object before the intruders fled on foot.

The injured man was found by his son a short time later, and emergency services were called.

Police attached to Coffs-Clarence Local Area Command and NSW Ambulance Paramedics attended; the man was stabilised at the scene before he was taken to Coffs Harbour Hospital.

He underwent surgery for a collapsed right lung, stab wounds to both his arms, and cuts to head, face and hands.

His condition is now believed to be stable and he has been able to provide police with a brief statement.

A forensic examination of the crime scene has been conducted and detectives are continuing their investigation into the incident.
