Three women have been arrested on suspicion of murder after a man was fatally stabbed.
The 47-year-old man was found injured at a property on Muirhead Avenue, in West Derby, Liverpool, at about 01:40 BST on Tuesday, Merseyside Police said.
He was taken to hospital where he was pronounced dead.
A 24-year-old woman from Anfield, a 49-year-old woman from West Derby and a 38-year-old woman from Litherland have been arrested in connection with the incident.
Det Ch Insp Steve McGrath said: "An investigation into this tragic incident is still in the early stages and as part of initial inquiries we have arrested three people.
"We are looking to establish the circumstances and I would discourage anyone from speculating while this work is being carried out.
"Although we have made these arrests, we are still appealing for information and if you can help our investigation, please come forward as a matter of urgency."
The force has appealed for anyone with CCTV or dashcam footage taken in the area around the time of the incident to come forward.
