A New York prison guard was severely injured Sunday morning by a package that exploded at his home north of Utica, authorities said.
The 52-year-old man, who was not identified, received "serious burns to his body" and was being treated at a Syracuse hospital, Gov. Andrew Cuomo said in a statement.
Oneida County Sheriff Robert Maciol said it was unclear whether the incident was connected to the officer’s work at the New York Department of Corrections and Community Supervision.
In a statement, Maciol said the package was left near the mailbox of the guard’s home in the town of Floyd. When the man picked it up about 8 a.m., Maciol said, the package exploded, leaving him with "sustained burns to his upper extremities."
Several law enforcement agencies were assisting in the investigation, Maciol said, including the FBI and the U.S. Bureau of Alcohol, Tobacco, Firearms and Explosives.
