Notebook vendor Rock Group has gone into administration, according to a statement on its website.

The statement blames the failure on "cash flow difficulties" as a result of "stock misappropriation by a former employee".

Dominic Wong and David Langton of Deloitte and Touche have been appointed joint administrators.

A skeleton staff has been retained while attempts are made to sell the business as a going concern. The company statememt said: "The administrators are currently liaising with a number of potentially interested parties in this regard."

Unconfirmed web reports said UK mobile content company Rok Entertainment had bought a controlling interest in Rok.
