Former Motorola exec accused of destroying evidence

Motorola has escalated the legal battle with its former chief financial officer Paul Liska, accusing him of deliberately destroying evidence related to a case made against the company.

Liska filed suit shortly after he left Motorola in the wake of a $3.6bn quarterly loss. He then claimed that the company had included misleading figures in its financial filings.

According to multiple reports citing unsealed court documents, Motorola's latest claim is that before Liska left the company and filed suit, he destroyed important evidence by erasing data from his company notebook.

The case is the latest in what has been a rough period for Motorola and its embattled handset unit.

Looking at an estimated 50 per cent year-over-year sales drop, Motorola is hoping to turn its mobile fortunes around with new smartphones expected later this year based on Google's Android operating system.
