The family of murdered Bristol schoolgirl Beck Watts have been left "devastated" at her death, following the recent discovery of her body parts at a Barton Court home.
Avon and Somerset arrested a further five people at the address last night - three men and two women - on suspicion of assisting a crime.
Two suspects - a 28-year-old man and a 21-year-old woman - were arrested on Saturday on suspicion of kidnapping the teenager and were arrested on Monday (2 February) on suspicion of murder.
A family statement said: "We are devastated to be told of this latest development.
"We are at an utter loss to understand why anyone would want to hurt our beautiful Becky in such a brutal way.
"We are grateful to the police for all they have done and are continuing to do in this investigation.
"Whilst there are people in custody, none of whom are connected to the Watts family, we will not be making any further comment and we ask that our privacy is respected at this horrific time."
The schoolgirl was last seen on 19 February by her step-mother Angie-Mae Galsworthy when she left her Crown Hill home with her phone, laptop and tablet device.
A police search was widened at the weekend as the focus turned to a black Vauxhall Zafira that was seized by police.
