The man on trial for murdering Tia Sharp searched online for pornographic pictures of young girls, a court has heard.

Searches were found on the web browser of Stuart Hazell's phone, jurors at the Old Bailey were told.

Prosecutors claim Hazell, 37, sexually assaulted 12-year-old Tia, the grand-daughter of his then-partner Christine Bicknell, then killed her and hid her body in the loft of the house they shared in south London.

Earlier, the court heard the window cleaner wrote to his father Keith Hazell from prison, insisting Tia's death had been an accident.

He denied any sexual motive for his actions, saying: "They're trying to say it was sexual but I promise you it wasn't."

But junior prosecutor Jocelyn Ledward yesterday told the jury that adult and child pornography was found on a memory card hidden in a cupboard at Hazell's house. There were also stills and moving footage of Tia asleep, and the image of a naked girl that prosecutors claim is Tia after she died.

The case was adjourned to Monday morning.
