A murder investigation has been launched after the discovery of a woman's body.
Police were called just before 1pm today to Queen Street in the Farnworth area of Bolton after receiving a call from the ambulance service.
Officers attended and found a woman dead at the scene.
Formal identification of the 31-year-old victim has yet to be carried out.
A spokesman for Greater Manchester Police (GMP) said a Home Office post-mortem examination will be carried out to establish the exact cause of death, but the death is being treated as suspicious.
Police in Bolton, together with detectives from Greater Manchester Police's (GMP) major incident team, have launched an investigation.
Superintendent Steve Nibloe, from GMP, said: "Clearly there will be very understandable anxiety in this community at the death of this young woman.
"First and foremost, our thoughts are with this woman's family following her tragic death.
"Although this investigation is only a few hours old, I want to try and reassure people who may be concerned that at this stage we do not believe this was a random attack.
"We know people will be shocked and upset and even worried, but I would like to stress that there is no reason for them to be fearful.
"However, there will be an increased police presence in the area in the coming days so I would urge anyone with concerns to approach an officer and speak to them, in confidence if needed.
"Our inquiry is now focused on trying to locate the person or persons responsible and I would also appeal to anyone who has information to come forward."
Anyone with information should call police on 101 or the independent charity Crimestoppers, anonymously, on 0800 555 11.
