Mark Lewis of Taylor Hampton Solicitors has issued a statement on behalf of Bob and Sally Dowler
It has been reported that contrary to what the Metropolitan police had said to the Dowler family earlier this year [they] now suspect that the "false hope" moment may not have been caused by the News of the World's use of Glenn Mulcaire. As Bob and Sally Dowler have always said it is not known whether the deletions were by Glenn Mulcaire or another person from the News of the World.
What is known is that the deletions were not automatically triggered by Milly.
The mobile telephone company's records show that Milly's last call on her own phone was made on Wednesday 20 March 2002.
Automatic deletion triggered by Milly would have happened (at the latest) by Saturday 23 March 2002. The deletions that gave false hope to the Dowler family happened after that date and therefore were caused by someone else accessing her voicemail.
The Metropolitan police now say that an email indicates that Glenn Mulcaire was instructed in writing after the Dowler family's hopes were cruelly raised.
Whether Mr Mulcaire was verbally instructed by that individual earlier, or whether the deletions were triggered by someone else is not known.
It is known that a News of the World journalist indicated in 2002 that he had obtained Milly's phone number and the PIN number required to access her voicemails from a source other than Glenn Mulcaire.
During the course of the original investigation, Surrey police were in touch with very senior journalists from the paper.
A consequence of their discussions was the radical alteration in the later editions of a story which had appeared in the first edition of the News of the World of 14 April 2002.
A formal investigation into the role of individuals at Surrey police is being undertaken by the IPCC. The Metropolitan police are investigating the activities of individuals at the paper. At this stage it would not be appropriate to make further comment about those concerned.
It remains unchallenged that the News of the World listened to Milly Dowler's voicemail and eavesdropped on deeply personal messages which were being left for her by her distraught friends and family.
By listening to messages, deletions occurred even if no conscious act of deletion had been undertaken. This was why Mr Rupert Murdoch apologised to the Dowler family and conceded that his newspaper's behaviour had been abhorrent and a letdown to his father's memory and to his mother's standards.
The Dowler family ask again that people leave them alone to grieve in peace. They have suffered enough in 2011 from the traumatic trial of Levi Bellfield and the horrendous actions of individuals hacking into Milly's voicemail. Enough is enough.
