The Ohio man who attacked four restaurant patrons with a machete and was later killed by police was under the attention of the FBI, NBC News reported.
Agents watched Mohamed Barry four years ago for making radical comments, but moved on, officials said. They did not elaborate on the nature of the radical comments.
Barry, 30, attacked patrons at Nazareth Restaurant and Deli in Columbus on Thursday. He was shot and killed by police after a chase following the rampage.
The survivors of the attack were identified as William Foley, 54, Neil McMeekin, 43, Gerald Russell, 43, and Debbie Russell, 43.
Police are still unclear as to what motivated the attack.
