LAS VEGAS (AP) — The fired former chief executive of Las Vegas Sands Corp.’s Macau casinos alleges in court documents revealed Thursday that billionaire Sheldon Adelson personally approved of prostitution and knew of other improper activity at his company’s properties in the Chinese enclave.

Brad Brian, an attorney representing Las Vegas Sands Corp. and Sands China Ltd., called the allegations false and “scurrilous” and claimed they had been included in the civil lawsuit brought by former Sands executive Steven Jacobs only to sensationalize the case.
