Police have renewed their appeal for help as a murder investigation in Bournemouth enters its fourth day.
A 34-year-old woman from Poole, named by the BBC and other outlets as Amie Gray, was stabbed to death on Durley Chine beach on Friday night.
A second woman, aged 38 and also from Poole, sustained serious injuries and is still receiving treatment in hospital.
Police have issued CCTV images of a suspect and have asked that anyone recognising him, or with other information, should contact them immediately.
A 17-year-old boy from Lancashire arrested on suspicion of murder has been released without charge and eliminated from enquiries.
The beach has been closed between Bournemouth Pier and Alum Chine while investigation work continued.
Flowers have been placed near the cordon.
Detective Superintendent Richard Dixey, of the Major Crime Investigation Team, said: “We need the public’s help to identify the suspect in the CCTV images. If you recognise him or have any information, no matter how small, that may lead us to his identity please get in touch immediately.
“We would ask the public not to approach a suspect under any circumstances, but to call 999 immediately.
“If you were on Durley Chine beach during the night from Friday 24 May to Saturday 25 May 2024 and saw the man pictured or any suspicious activity, we need to hear from you.
“We also are renewing our appeal to anyone who was in the area of Durley Roundabout, West Cliff Gardens, Durley Gardens or West Cliff Drive during that night.
“Did you see anyone acting strangely, mainly between 10pm and midnight? Do you have dashcam or CCTV footage that may assist the enquiry?”
