The family of the New York terror attempt suspect, Akayed Ulah, said they are “heartbroken by the violence” that occured in New York City Monday morning.

"We are heartbroken by the violence that was targeted at our city today, and by the allegations being made against a member of our family," the family said in a statement.

The statement was read aloud in front of the Ullah family’s Brooklyn home by Albert Fox Cahn, legal director for New York chapter of the Council on American-Islamic Relations, ABC News reported.

"But we are also outraged by the behavior of law enforcement officials who have held children as small as 4 years old out in the cold and who held a teenager out of high school classes to interrogate him without a lawyer, without his parents," the family added in their statement.

"These are not the sorts of actions that we expect from our justice system, and we have every confidence that our justice system will find the truth behind this attack and that we will, in the end, be able to learn what occurred today."

It’s uncertain who the minors referenced are.

Ullah was identified as the suspect in Monday morning’s bombing and allegedly wore an “improved low-tech explosive device” attached to himself. As Ullah was walking through a tunnel connecting the Eighth Avenue subway lines to the Seventh Avenue subway lines, the device detonated. He burned himself and injured several other people.

Ullah is an immigrant from Bangladesh, who first arrived in the U.S. in February 2011 with a F-43 family immigrant visa, according to the White House. He received a green card and is a legal permanent resident.

He told investigators he carried out his plans in the name of the Islamic State and had read terrorist propaganda. He used online resources to learn how to create the explosive device, according to media reports.

Ullah is in custody and is receiving treatment for his injuries at Manhattan’s Bellevue Hospital, according to law enforcement authorities.

New York Gov. Andrew Cuomo instructed state agencies, such as the New York State Police and the Metropolitan Transportation Authority, on Monday to boost security at New York airports, bridges, tunnels, and mass transit systems in response to the attempted attack.
