The first officer lost his right eye due to the attack.“When El Bahnasawy was restrained, a note was found in his sock that read, ‘This is a terrorist attack for the Islamic State.’ A pledge of allegiance to the Islamic State of Iraq and al-Sham (ISIS) was also found taped to the inside of a locker door in Bahnasawy’s prison cell,” the Department of Justice stated..US DOJ officials arrest assassination plotter with ties to Iran; implicated in Trump shooting.El Bahnasawy pleaded guilty to multiple charges, including assault, assault with intent to commit murder, possession of contraband in prison, and providing material support to ISIS, a designated foreign terrorist organization.He had previously been sentenced to 40 years in prison for orchestrating a series of planned attacks in New York in support of ISIS.US authorities said El Bahnasawy coordinated via encrypted messaging apps with Talha Haroon, a 20-year-old US resident living in Pakistan, and Russell Salic, a 38-year-old Filipino citizen, to target crowded areas during Ramadan in 2016.“He planned to detonate bombs in Times Square and the New York City subway system, and to shoot civilians at concert venues.
