• Stuart Hazell allegedly in high security Belmarsh prison
• Today he appeared before the Old Bailey charged with her murder

Tia Sharp's accused murderer is being kept under 24-hour watch after prisoners have threatened to kill him, it is being claimed.
Stuart Hazell, the 12-year-old's step-grandfather is in isolation in Belmarsh Prison, in Woolwich, south east London, where some of the country's most dangerous criminals are kept.
The Sun reported that the 37-year-old is being kept on a secure wing in the Category A prison alongside paedophiles and rapists.

Inmates are screaming death threats and calling his name from their cells, The Sun claimed.
A spokesman from the Ministry of Justice refused to confirm which prison Hazell is being kept in.
Today he appeared at the Old Bailey charged with murdering the schoolgirl between August 2 and 11.

The step-grandfather is due to face trial in January next year over her murder.
Tattooed Hazell, 37, wearing an orange t-shirt and black trousers spoke only to confirm his name and the fact he could hear proceedings as he sat emotionless throughout ten minute hearing.

He appeared via video link from Belmarsh, the UK's top security prison, sitting at a table next to a prison guard as the dates for his case were set down.
Unemployed Hazell was charged after Tia's body was found in the loft of the home he shares with his partner and Tia's grandmother Christine Sharp on Friday August 10.
Hazell is being represented by top barrister Lord Alex Carlile QC, who successfully defended Princess Diana's Butler Paul Burrell and carried out a review of the government's anti-terror laws.
He is receiving legal aid for both his QC and a junior counsel.
Lord Carlile warned: 'We do not know what the case against this defendant is, there has been some speculation in the media for example about the cause of death but there is no evidence whatsoever, it is no more than speculation.
'It would be dangerous and possibly foolish to to indulge in speculation that may run the risk of prejudicing a fair trial. We have no idea what the issues will be until we have at least the scientific evidence.
'It is also possible there will be a lot of factual background, with some eminating from family members.'
But as the trial will be heard by a High Court Judge a trial date in January 2013 was provisionally set.
Hazell is expected to enter his pleas at a hearing on November 19.

Tia's body was eventually found on Friday at her grandmother Christine Sharp's home in New Addington, Croydon - eight days after she was reported missing and after police had searched the home on several occasions.

Hazell is the boyfriend of Mrs Sharp, 46, who was arrested on suspicion of murder but bailed on Sunday pending further inquiries, along with her next door neighbour Paul Meehan, 39, who was bailed on suspicion of assisting an offender.
Detectives suspect the schoolgirl was probably smothered before her body was hidden in the attic.
A pathologist found no obvious major injuries to her body, leading to the theory that she was smothered or strangled.
An initial examination apparently uncovered bruising but forensic experts have been hampered by the badly decomposed state of the corpse when it was finally recovered from the sweltering roof space last Friday.
Although Tia had clearly been dead for some time, officers have not been able to rule out that the schoolgirl was alive when colleagues first visited the council house in New Addington, near Croydon, South London, after she vanished a week earlier.
Her father, Steve Carter, has demanded 'justice' for his little girl.
Mr Carter, 30, said: ‘I just want to get justice for my daughter, the proper way.
‘The last time I saw Tia she jumped in my arms. She told me about her school and what she was doing. She called me Dad. I’ll miss her for ever.’

A serious case review has been launched into the death of the little girl.
Serious Case Reviews are carried out when a child has died to look at the role played by local agencies in the life of that child and their family. The review aims to find out if any lessons can be learned about ensuring children’s safety.

Merton Council, which has responsibility for Mitcham, where Tia had lived with her mother Natalie, said it was 'standard procedure' to carry out a review.
Chief executive Ged Curran said: 'Our thoughts and condolences go out to all those who knew Tia.
'The local safeguarding children board will now commission a serious case review, the standard procedure in a tragic case such as this. The review will be assisted by the police, health services and local authorities.'
