A voice was apparently heard pleading for mercy before a young mother was kidnapped from her home and killed.

Kirsty Treloar, 20, was abducted shortly after 7am on Monday and was found dead in an abandoned car some 90 minutes later.

Neighbours said they heard a "hysterical" scream come from the property and a cry of "Please, please, please" before Ms Treloar was taken away.

Her body was discovered with stab wounds at around 8.30am in a grey Fiat Stilo which was abandoned about a mile from her home in Hackney, east London. She was pronounced dead at the scene, in Ryder Mews.

It is understood police believe it to be a domestic incident.

A 22-year-old man and a 24-year-old woman - believed to be Ms Treloar's siblings and named in reports as Dean and Gemma - were also injured in the attack and were treated for stab wounds.

Forensics officers have been examining both scenes, which were cordoned off with police tape. A tarpaulin covered one of the ground-floor windows of Ms Treloar's home in Brownlow Road.

One neighbour, who asked not to be named, said he heard what sounded like a window breaking early on Monday morning and a person shouting "Please, please, please".

Another woman living close to the three-storey property described how she was woken at around 5.30am before hearing "a female sounding extremely distressed".

The woman, 45, who did not want to be identified, added: "I thought it might be foxes fighting, which can sound quite human. Then I thought, 'No, it's definitely not', it sounded like a young woman in distress. It was very short-lived and stopped quite abruptly. It sounded like she was a bit hysterical."
