ALBANY, N.Y. — Federal officials say a nurse at the Veterans Affairs hospital in Albany tampered with pain medication given to patients.

The U.S. Attorney's Office says 30-year-old Nathan Baum of East Greenbush, New York, was indicted Wednesday for allegedly tampering with a consumer product and obtaining controlled substances by deception and subterfuge.

Authorities say Baum is a licensed practical nurse who works at the Veterans Affairs Medical Center hospice ward in Albany. They say that during a five-week period in the spring of 2014 he removed the oxycodone hydrochloride from at least 25 syringes and replaced it with an anti-psychotic medication that's used to treat certain mental disorders and uncontrolled movements or agitation.

Baum was arraigned on Friday and released. It couldn't be determined if he has a lawyer who could comment on the charges.
