Becky's step-brother and his girlfriend named as murder suspects

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.

Becky's stepbrother Nathan Matthews has been charged with her murder.

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

Officers have been given more time to question the four men and one woman arrested on Monday.

The five, all in their 20s, were arrested on suspicion of assisting an offender and they will remain in police custody for a further 24 hours.

Bristol Magistrates' Court granted the extension earlier today.

Becky's Uncle, Joe Galsworthy, has released an emotional letter:

Becky Watts' family have laid flowers at her St George Home surrounded by a media scrum:

The reported arrest of Becky Watts' stepbrother and his girlfriend in connection with her suspected murder "continues to haunt" her family, her brother said.

Dan Galsworthy posted an emotional message on Facebook revealing his turmoil.

He said: "This has left a deep hole in my heart and will continue to haunt me.

"To everyone messaging and supporting me I haven't replied to any messages because I simply have no words, I thank you all and deeply appreciate everyone's support. Love to you all."

Matthews is understood to be the son of Anjie Galsworthy, 49, who is married to Becky's dad, Darren, 51, who fathered her and Dan with their mum Tanya Watts, 46.

Detectives are also questioning four men, two aged 29 and two aged 23, and a 23-year-old woman, who have been arrested on suspicion of helping an offender.

The first picture has emerged of the couple suspected of killing Becky Watts.

Seen here in fancy dress, Shauna Phillips and Nathan Matthews, are being held in police custody.

Officers have until this afternoon to either charge or release them.

Police confirm the female suspect, who is reported as being Shauna Phillips, was taken to hospital last night after feeling unwell.

She has since returned to custody.

Hundreds of flowers have been placed outside Becky's St George home.

This follows the tragic news that body parts were discovered in the search for the missing 16-year-old.
