Four more people have been charged in connection with the murder of British teenager Becky Watts.

Karl Demetrius and Donovan Demetrius - both aged 29 - along with Jaydene Parsons (23), all of Barton Court in Bristol, have been charged with assisting an offender.

James Ireland (23) of Richmond Villas, Avonmouth, faces the same charge.

They have been remanded in custody and are due before Bristol Magistrates' Court later.

A fifth person, who was arrested on Monday, has been released without charge.

It comes after Becky's stepbrother, Nathan Matthews, appeared in crown court for the first time charged with her murder.

Matthews appeared via video link unshaven in a grey sweatshirt and in a hearing that lasted 15 minutes he spoke only to confirm his name.

Prosecutor James Ward told the court: "The allegations of this case have been well-rehearsed in the press recently and I do not propose to go into the finer details."

"There are still people helping the police with their inquiries. Therefore, it would be wrong to place before the media further details about this case."

Mr Matthews was remanded into custody and will next appear before a judge on March 26th.

On Thursday he appeared before Bristol magistrates with his girlfriend Shauna Hoare (21).

Ms Hoare is charged with intending to pervert the course of justice and will also appear in Bristol Crown Court on March 26th.

Becky (16) disappeared from her home in the St George area of Bristol on February 19th.

Police launched a huge search for the teenager and a social media campaign that reached millions of people.

Body parts were later found at a house in the Barton Hill area of the city.

Bouquets, teddies and cards have been left at Becky's home, as well as at Barton Court, and mourners have attended churches across the city to pay their respects.
