Investigators said victims were videotaped while using the bathroom at Expedia’s Seattle campus. Now, a class action lawsuit claims Expedia’s security contractor Securitas knew about the secret cameras weeks before the authorities caught the suspect — a former Expedia worker.

The lawsuit comes after a former Expedia employee was charged with four counts of voyeurism following the discovery of bathroom spy cameras at the company's Interbay campus.

Attorneys accused international security company Securitas of mishandling an investigation into spy cameras found in bathrooms on Expedia's campus.
