The father of Ahmad Khan Rahami who was arrested on Monday after exchanging fire with the police and is suspected of carrying out two bomb attacks, one in New York and the second in the state of New Jersey, that wounded 31 people, said that he had informed the Federal Bureau of Investigation (FBI) that his son “was radicalised and was obsessed with extremism” after returning from Afghanistan two years ago.

In a telephone conversation with the American news agency the Associated Press (AP), Mohammad Khan Rahami said that “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 also added that he does not think that the FBI investigated his son at the time. However, after the incident, the FBI began to investigate by talking to Mohammad Rahami, who is “fully cooperating” with them. He added: “I strongly condemn what my son did. I feel sad because people have been injured”.

Ahmad Khan Rahami,28, was arrested on Monday after a clash with police in Linden (New Jersey). Yesterday, his lawyer told the New York Times that he is being treated at a hospital in New York for injuries sustained whilst he was being arrested. The lawyer declined to identify the name and location of the hospital.
