A man has been arrested on suspicion of murder following the death of teenager believed to be a missing 17-year-old girl.
The girl, named as Catherine, was reported missing on Saturday, Greater Manchester Police (GMP) said.
Inquiries led officers to an address in Whalley Close in Ashton-under-Lyne, Tameside, at around 9am on Sunday.
A girl had died at the scene and GMP said the time and cause of her death are not yet clear.
Officers believe she is Catherine, though formal identification has not yet taken place, and her next of kin are being supported by specialist officers.
A 55-year-old man was arrested on suspicion of murder and remains in police custody but detectives are âfollowing several lines of inquiryâ.

Detective Chief Inspector Anna Barker said: âFirstly, our thoughts are with the family and friends of the young person who has tragically lost their life, who we sadly believe was missing Catherine.
âAlthough we have a man in custody, our investigation team is keeping an open mind and are following several lines of inquiry.
âA scene will remain in place while officers conduct their investigation. If you have any concerns, please speak to an officer who will listen to you.
âWe are trying to get all the answers we can for the family of this young person who is at the forefront of the investigation teamâs mind.â
She added: âWe are appealing for anyone who may have been in the area of Whalley Close on the Saturday and early hours of Sunday morning to come forward and assist us in our inquiries.
âEvery piece of information, no matter how small it might seem, helps us build a clearer picture in this investigation.â
