The British government has admitted another data loss blunder: Its bankruptcy agency has lost a laptop carrying personal information on more than 100 former company directors.

The Insolvency Service says four laptop computers were stolen from its office in the northern English city of Manchester. It says one of them carried documents that "may give cause for concern."

The service said Wednesday that information on 122 former company directors was lost in the theft, as well as information on an unknown number of creditors, investors and employees.

Britain's government has been humbled by a series of data losses even as it attempts to roll out an ambitious national identification card. Medical, prison, and military records have been stolen or disappeared in recent months.
