A street has been sealed off by police and a forensic tent set up outside a property.
The police cordon has been in place since the early hours on Moss Lane in Swinton, at the junction with Borsden Street.
Eyewitnesses say a white police tent can also be seen outside a property.
Greater Manchester Police confirmed they were called to an incident on the street but have not yet released any further details.
It's believed emergency services were seen in the area since 11.15pm last night and the cordon appeared shortly afterwards.
