Narrative:

Friday night flight to ZZZ, 137 passenger, with a full moon. The fasten seatbelt sign had been on for the entire 40 min flight because of light chop. Just as we started to turn base leg, the flight attendants called and said that the aft lavatory door handle had fallen off, trapping a passenger in the aft lavatory. They said that part of the latch had fallen down between the door panels, and they and the passenger had tried numerous things but could not open the door. I slowed to approach speed, and told them to keep trying, and I would let them know when we were about 2 mins away from landing. If we couldn't get him out by then, he would have to situation in the lavatory and brace himself on the front of the compartment for landing. About 2 mins out, I called the flight attendants and they had not gotten the door open, so I had them tell the passenger to situation and brace himself on the front of the compartment and for them to take their seats. I made a soft landing and used gentle braking and reverse to stop the aircraft. Maintenance had to break apart what was left of the latch to open the door and free the passenger.
