The cockpit voice recorder from the AirAsia plane that crashed into the Java Sea last month carrying 162 people was recovered Tuesday and taken to an Indonesian navy ship, an official said.

"The CVR (cockpit voice recorder) has been found and lifted from the sea," said an official involved with the search, who requested anonymity.

The official added that the device had been taken to the navy ship Banda Aceh.

Divers had already retrieved the other black box, the flight data recorder, from the sea on Monday.

The recorders hold vital information about the last moments of flight QZ8501, which crashed on Dec. 28 as it flew from Indonesia's Surabaya to Singapore, and will help investigators to find out what caused the accident.
