On Saturday morning, 86-year-old Betty Zengel, who suffers from Alzheimer's, managed to disappear from her caretaker's watch on the Upper East Side—and somehow ended up outside a Chelsea nightclub at midnight. M2 Ultralounge's owner and head of security contacted the NYPD, whose officers escorted Zengel away. But later the club's owner and security noticed Zengel wandering in the rainy streets a few blocks away—and now the club claims the NYPD abandoned Zengel.
