A man was hit about the head with a hammer after masked intruders broke into his Bury home.
Officers were called to Gawthorpe Close, Bury, shortly after 2.30am on Monday 21 July 2014.
On arrival they established two men had forced their way into the house and assaulted the 35-year-old occupant with a hammer.
He has been taken to hospital for treatment to a serious head injury.
A woman and two children were inside the house at the time but were not physically injured.
An investigation into the circumstances surrounding the incident and those responsible is underway.
Chief Inspector Amber Waywell, said: â€œTwo men have forced their way into a family home and violently assaulted a man with a deadly weapon.
â€œHe has been hit over the head with a hammer and without question could easily have been killed.
â€œThere appears to have been little or no demand for property or similar so it would seem to be a deliberate and targeted assault.
â€œIt is shocking that anyone is prepared to commit such acts of wanton violence in the first place, let alone in the presence of a mother and her children and we will do everything we can to establish exactly what has gone on and more importantly who is responsible.
â€œIf anyone has any information that can help us I would encourage them to contact us in complete confidence.â€
