Speaking to The Associated Press early today in a telephone interview, Mohammad Rahami, father of alleged bomber Ahmad Khan Rahami, said his son underwent a personality shift after visiting Afghanistan and Pakistan in 2013.
Speaking in Urdu, Mohammed Rahami said his son was not the same after that trip.
"I found a change in his personality. His mind was not the same. He had become bad and I don't know what caused it but I informed the FBI about it," he said.
"I condemn the act of my son and I am sad over injuries caused to people," he said, adding that he was cooperating fully with investigators.
Rahami, an Afghan-born US citizen was shot and severely injured during his arrest Monday. He has been unconscious and intubated for much of the time since undergoing surgery, said Robert Reilly, a spokesman for the FBI's Newark office.
