The flight was deviating around thunderstorm activity and while descending the aircraft encountered turbulence resulting in a broken ankle to a passenger. A company representative reported, "Before starting the descent from FL280 to FL240, an announcement was made to the cabin that the FASTEN SEATBELT sign was on and that turbulence was expected during the descent." In a written statement the First Officer reported, "After we encountered the turbulence, we contacted the purser via the interphone. The purser informed us that there was one passenger in a lavatory with an injury to the head, and a second passenger also in a lavatory with a broken ankle." The male passenger received a serious trimalleolar fracture to the left ankle, and the female passenger received a minor injury. The male passenger reported he had unfastened his seatbelt and proceeded to the lavatory at the rear of the airplane. He reported that the fasten seat belt sign was not illuminated when he left his seat, and the flight deck had not issued any advisories while he was waiting for the lavatory. He reported that while he was in the lavatory, the airplane encountered turbulence that led to his injury. The female passenger, who received a minor injury, reported she was in the lavatory when the airplane encountered turbulence.
