At around 11.15pm last Tuesday (May 9), officers responded to reports of an aggravated burglary in Fir Tree Avenue.
It is believed four men entered a property and threatened the occupants with bladed weapons.
Shortly after, they stole a car from the property.
Officers are now appealing for anyone who may have witnessed the incident or heard something from around that time.
Detective Inspector Andrew Fink, of GMP's Oldham Division, said: "This was a shocking incident in which a family were threatened in their own homes.
"We have zero tolerance for these sort of shocking acts and we are determined to bring those responsible for this crime to justice.
"Our officers are working hard to establish all leads and information, and any information that the public may have would be of great assistance to their enquiries.
"I would urge anyone with CCTV, dashcam, or doorbell footage to please get in touch.
"No matter how small you think the information is, it could be of great use for the investigation."
Anyone with any information is asked to contact police on 0161 856 8962 quoting log number 4272 of 9/5/23.
