Becky Watts' stepbrother 'held over her murder'

Becky Watts' stepbrother and his girlfriend are reportedly being held by police over the 16-year-old's murder.

Police are questioning a 28-year-old man and a 21-year-old woman in connection with the alleged killing, which turned into a murder inquiry when officers found body parts at a house yesterday.

Nathan Matthews and Shauna Phillips have been named in several newspaper reports as the pair.

Officers were last night granted a further 24 hours to question them but must either charge or release them by this afternoon.

A further four men and one woman have also been arrested on suspicion of assisting an offender.
