Exclusive HP has suspended more than 100 employees on full pay in the UK and Ireland pending an investigation into the misuse of its corporate email system to circulate pornographic material.

Fifteen people were dismissed on Tuesday morning for gross misconduct, sources told us. HP, however, tells us this figure is inaccurate and that "less than five" people have been dismissed as part of the investigation.

An investigation of the circulation of inappropriate material at the computer giant was initiated by HP’s UK board, after the issue was forcibly brought to its attention when one of its directors received pornographic material in his email, we understand.

HP confirmed that it was investigating the misuse of its systems but said it was unable to comment in detail on the situation, beyond sending us a prepared statement, until its investigations are complete.

“HP can confirm that it is currently investigating the misuse of the company email system that contravenes its internal policy for all employees. HP can confirm that this involves the viewing and sharing of unauthorised and inappropriate material. This matter is being addressed with the utmost urgency through HP's internal investigatory procedures.”

“HP takes any allegations of the misuse of corporate resources extremely seriously and has acted swiftly to initiate an internal investigation. Once the results of the investigation are available, HP will, where necessary, apply its standard disciplinary process and take appropriate action.” ®
