New York blast suspect Akayed Ullah had scribbled notes on his passport that expressed hate and rage towards the United States, said US prosecutors.
According to a report published by the New York Times, court documents say that Akayed’s passport contained multiple handwritten notes. One of them said: "O America, die in your rage."
Akayed detonated a homemade bomb strapped to his body at the Port Authority Bus Terminal on Monday. He and three others were injured in the attack.
After the blast, Akayed told police interviewers that “I did it for the Islamic State,” according to court papers filed by federal prosecutors.
According to the documents, he also told investigators that he had been motivated by American air strikes on Islamic State target.
The complaint stated that Akayed had used materials that included Christmas lights to make the device and it was affixed to his body with Velcro straps.
The 27-year-old Bangladeshi migrant was charged in a criminal complaint filed in Manhattan federal court with providing material in support to a foreign terrorist organization, bombing a public place, destruction of property by means of explosive and use of a destructive device.
According to the New York Times report, Akayed’s social life in Brooklyn revolved around Nur al-Islam Mosque and he was close to Gauhar Ahmed, the imam of the mosque.
Gauhar, claiming that he was not very close to the suspect, said Akayed had never indicated any radical tendencies.
He added that he had not seen Akayed in five or six years and only remembered speaking to him twice. The first time was at a spiritual discussion.
The imam said Akayed was too busy comparing religions and he had suggested to him to learn how to pray.
The second time Gauhar talked with Akayed was over the phone after the death of his father. Gauhar said he had called him to express his condolences.
Akayed immigrated to the US on a family visa in 2011. However, his wife did not join him in the US. She and other family members are now being questioned to try to understand how he was radicalised.
Inspector General of Police AKM Shahidul Hoque said Akayed had no criminal record in Bangladesh and had last visited the country on September 8.
Trump has taken the attack to drum support for his immigration ban, which, the White House said, would have prevented the attacker from entering the US.
