An investigation launched following the death of a 30-year-old Wigan woman continues a month on from the shock incident.
Detectives said 30-year-old Lyndsey Vaux died with a number of unexplained injuries and a 31-year-old woman has been arrested and bailed on suspicion of assault.
A spokesman for Greater Manchester Police said enquiries are ongoing with anyone with information about how Ms Vaux came by her injuries to come forward.
No further arrests have been made and a cause of death has still not been established, the police added.
Ms Vaux was taken to Wigan Infirmary in suspected cardiac arrest on Sunday May 22 but died shortly after.
A Home Office post-mortem examination revealed the unexplained injuries and the police investigation was launched.
Residents living nearby to a property on Sydney Street in Platt Bridge, understood to be Ms Vaux’s residence, spoke of a heavy police presence over that weekend.
Speaking in the days following Ms Vaux’s death, detective inspector Martin Reddington of Wigan division said: “Our thoughts are with Lyndsey’s family and friends at what is an incredibly sad time for them.
“We are investigating and trying to get a full understanding of what happened to Lyndsey leading up to her death.
“I would urge anyone who may have information about how she came by her injuries to get in touch police.”
Residents have taken to social media in recent weeks to pay tribute to Ms Vaux with a dedicated Facebook page set up by friends.
Fiona Singleton posted: “Rest in peace, lovely woman had a heart of gold, you will always have a place in our hearts.”
Vicky Vandoo posted: “We’re all going to miss you, heart of gold, do anything for anyone. My thoughts are with you and your family.”
Kristen Robinson said: “You will always be remembered by so many. My daughters will always know of the kindness you showed me when I needed help.
