Federal authorities have filed terrorism charges against a suspect for detonating a pipe bomb near New York City’s Port Authority Bus Terminal on Monday.

Akayed Ullah, a 27-year-old Bangladeshi national, pledged loyalty to ISIS before carrying out the attack, which left several people with minor injuries, according to authorities.

Ullah is charged with providing material support to a terror group, using a weapon of mass destruction, bombing a public place, destruction of property by means of fire or explosive and use of a destructive device during a crime of violence.

Rick Leventhal reported on "Outnumbered" today that the 10-page criminal complaint reveals that Ullah built the pipe bomb at his Brooklyn apartment, gathering at least some of the materials from job sites where he worked as an electrician.

The bomb was filled with explosive material and metal screws, and it used Christmas lights and a battery for detonation, Leventhal reported, adding Ullah attached it to his body with zip ties.

The complaint also says Ullah's radicalization began at least three years ago, and he began researching how to build improvised explosive devices about one year ago, Leventhal said.

He noted that the complaint reveals Ullah posted a message on his Facebook page Monday morning shortly before the attack: "Trump you failed to protect your nation."

According to authorities, Ullah acted alone and was not on the radar of the FBI or the NYPD.
