Becky's step-brother, Nathan Matthews, and his girlfriend, Shauna Phillips, are reportedly being held by police on suspicion of murdering the teenager. Officers must either charge or release them by this afternoon.
Police investigating the death of teenager Becky Watts say they have discovered her laptop, tablet and mobile phone.
The 16-year-old went missing last month and her remains were found at a property in Barton Hill last Monday.
She left home on February 19 with her phone, laptop and tablet but did not inform friends or family where she was going, or take extra clothes. Police began searching for the teenager, described as shy, after she was reported missing by her family at 4pm on February 20.

Forensic examinations, expected to last for several more weeks, will continue to establish the full circumstances surrounding her death.
