Two women arrested on suspicion of murder following the death of Lyndsey Vaux have been re-bailed.
The pair, aged 31 and 56, were arrested earlier this month.
They have been re-bailed until October 5.
Ms Vaux, 30, of Sydney Street, Platt Bridge, died in May having sustained “unexplained injuries”.
She was taken to Wigan Infirmary in suspected cardiac arrest on Sunday, May 22.
A Home Office post-mortem examination revealed the unexplained injuries and a police investigation was launched.
The exact cause of death is still to be confirmed.
