The incident occurred Wednesday afternoon at a medical building in Westbury, New York, according to the Nassau County Police Department.

Long Island Police say Keith McAllister defied orders to stay out of the MRI room, but his family tells a much different story.

A man died last week after being pulled into an MRI machine by a “large metallic chain” police said he was wearing around his neck – highlighting the importance of checking for any metallic objects before going near the powerful magnets used in the medical imaging machines.
