Officers attended and established that three men had entered the property before threatening and assaulting the occupant with a baseball bat whilst demanding money.
The victim sustained head, arm and torso injuries.
The offenders escaped with jewellery including high-value watches and the keys to a Land Rover Discovery, which was subsequently stolen from the driveway of the property.
At the time of the incident, the offenders were wearing dark-coloured clothing and masks.
DC Kavita Young, of GMP’s Oldham district, said: “Luckily, the victim wasn’t more seriously injured. Nevertheless, this was a traumatic experience for him.
