The “partial” remains were found by a member of the public near the Manor Steps Zig Zag, off Boscombe Overcliff Drive in Dorset, on Saturday, August 26.
Cops launched a murder investigation – and today revealed a 28-year-old woman and a 48-year-old man have been arrested.
Detective Inspector Neil Third, of the Major Crime Investigation Team, said: “This remains a very complex investigation and we have worked tirelessly since the initial discovery and report to progress our enquiries.
“Foremost, our thoughts are with the victim’s family. We will continue to do all we can to establish the circumstances of the death.
“Now that we have been able to identify the victim following scientific analysis, I am in a position to be more specific about my appeal.
“A number of cordons have been put in place across the Boscombe area and I would like to thank the public for their assistance while officers conduct their detailed enquiries,’ he said.
“Officers can be approached by members of the public with any information or concerns.”
