The FBI on Sunday identified the suspect as Malik Faisal Akram, 44, a citizen of the United Kingdom but did not say how or when he entered the United States.
Akram’s brother Gulbar posted on Facebook that the suspect, from the industrial town of Blackburn in the north of England, suffered from mental illness and said the family had spent all night at the Blackburn police station “liaising with Faisal, the negotiators, FBI etc.”
“There was nothing we could have said to him or done that would have convinced him to surrender,” Gulbar wrote on the Blackburn Muslim Community’s Facebook page.
He said the FBI was due to fly into the UK “later today,” saying that the family as a result could say little more.
“We would like to say that we as a family do not condone any of his actions and would like to sincerely apologize wholeheartedly to all the victims involved in the unfortunate incident,” the brother wrote.
