The plaintiff in a proposed class action on Thursday accused high-end retailer Lord & Taylor of negligence in failing to protect its customers’ private information, just days after the Hudson’s Bay Co. subsidiary announced that it had been the target of a massive data breach in its North American stores.

The lawsuit, filed in the U.S. District Court for the District of Delaware, alleges that Lord & Taylor failed to protect its payment system in the wake of a series of high-profile breaches to hit major retailers in recent years.
