Pictured: Man, 44, and woman, 48, accused of cutting up victim, 38, with power tools and dumping her remains in a Croydon park - as police search for her dismembered torso

This is the man and woman accused of cutting up a female victim with power tools before dumping the remains in a park.

Body parts belonging to Sarah Mayhew, 38, were found in Rowdown Fields in New Addington, south London last Tuesday.

A dog walker alerted the police to the grim discovery after their canine had uncovered a human bone in the morning. 

Arms, legs and a head were also found near the bone before they were identified as belonging to Ms Mayhew through a DNA test. 

However, the search for the 38-year-old's severed torso continues, the Old Bailey heard.

Gemma Watts, 48, and Steven Sansom, 44, were arrested on Saturday and subsequently charged with Ms Mayhew's murder and preventing her lawful and decent burial.

It is alleged that the couple killed Ms Mayhew at a residential property before her body was dismembered with power tools.

The cause of the victim's death is still unknown. However, an examination of her body found two small vertebrae were broken in her voicebox, bruising to the skull and her head had been shaved.

Ms Mayhew was last seen in Sutton, south-west London, on the evening of March 8.

Today, Sansom and Watts appeared separately at the Old Bailey before Judge Philip Katz KC.

Watts, of Featherbed Lane in New Addington, appeared first by video link from Bronzefield prison followed later by Sansom from Belmarsh jail.

Watts appeared to have a dark bruise around her eye and both defendants spoke only to confirm their identities.

The court heard that both she and Sansom are alleged to have killed Ms Mayhew at the residential property on the night of March 8 before disposing of the body.

Prosecutor Tom Little KC: 'This is quite a significant ongoing investigation in relation to the whereabouts of the entirety of the deceased's body.
