"We send hotel workers, housekeepers into rooms by themselves without any other staff, without any other security," Lancman said at a news conference Sunday outside the Sofitel Hotel, the site of Strauss-Kahn's alleged sexual assault of a hotel maid last week.

According to the report, Lancman said attacks on hotel housekeepers are common, and though the incidents "may not be as brutal or as sensational" as the allegations in the Strauss-Kahn case, housekeepers are often treated inappropriately. 

The proposed legislation calls for hotels to provide a small device for housekeepers that would, at the touch of a button, trigger an audible alarm or alert hotel security.

He estimated a cost of $20 to $40 per device, though he said it would cost "significantly less" for hotels to buy in bulk.

The Associated Press said a review of court documents and news reports found at least 10 other hotel housekeepers who say they've been attacked in the U.S. in the last three years.
