Phone hacking: mobile networks took almost six years to tell customers | Media | guardian.co.uk
Vodafone was “expressly told by police not to contact customers as we may prejudice any police investigation”.
A spokesman for Vodafone later said this had been a verbal request made in 2006, around the time of the arrests of the former News of the World royal editor Clive Goodman and Glenn Mulcaire, the private investigator who worked for the now defunct News International Sunday redtop. Both jailed for phone hacking offences in January 2007.
The spokesman added that in 2010 Vodafone wrote to the police to seek permission to notify customers but Scotland Yard never responded.
