Thaune Nunes Ferreira, 29, is facing charges of fraud after the local police, acting on an anonymous tip, found that she was using the prosthetic fingers on the biometric employee attendance device in order to cover the absence of her co-workers.
The police found six prosthetic fingers with Ferreira while 11 doctors and 20 nurses are said to be involved in the ploy.
Ferreira accused the coordinator of the Office of Mobile Emergency Care (Samu), Jorge Cury, for masterminding the ploy and said that signing in absent workers was one of the conditions for her employment. However Cury has dismissed the allegations and said, "The health secretary called me and I now I am going to the police station. This is absurd! I've been a city official for 25 years and I've never known of this happening."
