A woman who died after being found unresponsive at a home in Preston has been named locally as Sinead Lowry.
Emergency services were called to a home on Heywood Road, Ashton, at around 5.25am on Saturday.
The 24-year-old was taken to Royal Preston Hospital but pronounced dead on arrival.
A 26-year-old man, from Preston, initially arrested on suspicion of murder has since been released without charge.
But police have bailed the same man, until June 30, pending further enquiries in relation to allegedly being concerned in the supply of a Class A drug.
Tributes have been paid to Miss Lowry on social networking site, Facebook, following the sudden death.
Zoe Tuson said: “Another angel gained but far too soon.”
And Phoebe Browne said: “Never felt so much shock and pain like this, you [were] too young.”
Adele Parry added: “RIP to a beautiful young woman.”
