Akayed Ullah, the Bangladeshi suspect in Monday's pipe bomb explosion beneath New York's Times Square, gave a leaflet of militant leader Jasim Uddin to his wife and asked her to read it in September last indicating that he was self-radicalized, says a top police official on Wednesday.
Akayed's wife Jannatul Ferdous Jui came up with the information during an interrogation, said Monirul Islam, chief of Counter Terrorism and Transnational Crime (CTTC) unit of Dhaka Metropolitan Police (DMP).
Monirul said Akayed might have been self-radicalized through the internet after going to the US as he had no criminal record in Bangladesh.
He also said that police did not find Akayed's link to any militancy activities in Bangladesh.
Quoting Jui, the CTTC chief said she also discussed the content of the leaflet with her husband.
Akayed followed traditional Islamic clothes and rules strictly and offered prayers regularly during his last visit to Bangladesh, the CTTC chief added.
During his stay at home, most of the time he remained busy with his laptop, Monirul said quoting Akayed's wife.
"We are interrogating his family members to know further details about him," said Monirul.
During interrogation, Akayed's wife Jannatul Ferdous Jui revealed information about him.
Monirul said Akayed's wife informed police that Akayed had visited Bangladesh on September 18.
During his visit to Bangladesh, he visited outside of Dhaka several times but she does not know where he went.
He spent most of his time with family, Monirul said quoting Jui. He said that police now are interrogating Akayed's brother-in-law Joy.
Earlier, police detained Jui, his father-in-law Zulfikar Haider and mother-in-law Mahfuza Akhter from the city's Jigatala area on Tuesday for interrogation.
The CTTC team is interrogating them for the second day.
