The tech firm hired by News International for storing archived emails revealed on Wednesday that it was asked by the NI officials to delete messages on 13 different occasions within a span of 19 months.
HCL Technologies, which made this revelation, reportedly wrote to the home affairs select committee in order to update MPs on the issue. This was the second instance in the running month when HCL officially provided its assistance to the authorities looking into the phone hacking controversy.
Earlier in the month, the company stated that NI had asked it nine times to delete the material in question.
According to HCL it had discovered four previously unreported requests, which include the one in last December when NI asked it delete messages from the inbox of a user who did not access it for the past 8 years or so.
"The request for deletion of folders and emails by News International is concerning. The committee will continue to investigate the issue of phone hacking and the removal of any information that could possibly point to the prevalence of phone hacking by those working in the organisation," said Committee chairman Keith Vaz, Labour MP for Leicester East, the Guardian, UK reports.
