A hidden camera investigation by New York Attorney General Andrew Cuomo lead to charges against four workers at a Medford nursing home Tuesday.

The Medford Multicare Center for Living workers are accused of endangering the welfare of a patient. The alleged victim in the case is an 84-year-old man suffering from dementia and chronic heart failure, according to officials.

Cuomo says cameras caught two nurses and two nurse?s aides neglecting the man over a six-week period. Specifically, the state alleges the workers did not give the man water, turn him over in his bed or bathe him. One nurse is accused of not taking the man?s heart rate after giving him medication.

The lawyer for one of the accused, Rima Chaudry, says the nurse was following protocol. "I'd like to know why the attorney general isn't looking at the nursing home itself and the supervisors as to what this conduct consisted of,? says Chaudry?s attorney Oscar Michelen.

Chaudry pleaded not guilty to four misdemeanor endangerment charges and four felony counts of falsifying business records.
