Police are investigating a man's death after he was pulled into a Magnetic Resonance Imaging (MRI) machine earlier this week.

The 61-year-old man was wearing a "large metallic chain" when he entered an MRI room on Wednesday at Nassau Open MRI in Westbury, N.Y., while a scan was in progress, the Nassau County Police Department said.

The chain caused the man to be "drawn into the machine which resulted in a medical episode" and he died from his injuries the next day, police also said.
