The police are treating the death of two people who have fallen from a condominium in the south of London as suspicious.
Renata Poncova and Tony Taylor, both 33, died in Camberwell shortly after midnight on Saturday 3 November.
Scotland Yard said the detectives had discovered evidence at their eighth-floor apartment, as well as a possible disturbance to property before they fell, which indicated that there were suspicious circumstances.
The police were recalled to the scene at 11.44am on Friday 2 November, after receiving news that a man and a woman were injured after apparently having fallen from a height.
The paramedics were called to the address but Poncova and Taylor were declared dead on the spot at 12.30 in the morning.
An autopsy found both dead due to multiple injuries "consistent with being dropped from height".
DI Phil Coster said: "I appeal to anyone who knows Renata Poncova and Tony Taylor and has had contact with them in the days before their death, to call the police.
"I also need to talk to anyone who witnessed the accident or saw something suspicious during or before death.
"Home tests and a possible disturbance in the apartment before the fall lead us to believe that there are suspicious circumstances.
"We need witnesses to come forward to help us build a picture of what happened before these deaths." If you know anything, call us. "
