The son of an American police officer, who has a history of mental illness and was on probation for drinking, has been charged in connection with an alleged terror plot, officials said Monday, according to the AFP news agency.
Alexander Ciccolo, 23, also known as Ali al-Amriki, was arrested on Independence Day in the northeastern state of Massachusetts and is due to appear in court to answer firearms charges on Tuesday, the report said.
He was detained after allegedly taking delivery of four weapons — two rifles and two pistols — from an FBI informant. Prosecutors said he had a knife strapped to his waist at the same time.
They allege that he is a supporter of the Islamic State (ISIS) jihadist group, who wanted to wage a gun and bomb attack on college dorms and a cafeteria that would be broadcast live on the Internet.
Partially made Molotov cocktails were found in his apartment and he was monitored buying a pressure cooker similar to that used in the 2013 Boston Marathon bombings, court papers allege, according to AFP.
The charges come a week after the head of the FBI, James Comey, briefed the Senate select committee on intelligence that upwards of 200 Americans have traveled or attempted to travel to Syria to join up with ISIS.
But court documents unsealed on Monday portrayed a disturbed Ciccolo, an individual with "a long history of mental illness" who was put on probation in February for a drinking conviction.
While in custody, he stabbed a nurse's head with a pen during a routine medical exam that left a hole in the skin and broke the pen in half, court papers said.
In the 18 months prior to his arrest he became "obsessed with Islam," prosecutors claim.
Last year, the 13th anniversary of the September 11, 2001 attacks, the FBI was tipped off that Ciccolo allegedly had expressed a desire to go to Iraq or Syria to fight for ISIS.
The FBI says that he operated a Facebook page under the name Ali Al Amriki, that was a platform for extremist postings.
Under the photo of a man holding a machete, was written "another day in the forest strengthening myself" and next to the image of a dead American soldier, was written "Thank you Islamic State!"
Last month, he allegedly told an informant about his intention to travel inter-state to bomb two bars and a police station, before switching his focus to attacking a university instead.
Further concerns were raised by Ciccolo's alleged praise of the June 26 massacre of 38 foreign holidaymakers on a beach in Tunisia, which he is accused of calling a "huge accomplishment."
His family issued a statement through the Boston police department saying they were "saddened and disappointed" but thanking authorities for preventing "any loss of life or harm to others.
"At this time, we would ask that the public and the media recognize our grief and respect our desire for privacy," they were quoted as having said.
His police captain father was reportedly one of the first responders to the 2013 Boston Marathon bombings that killed three people and wounded 264 others, carried out by brothers of Chechen descent.
A string of Americans were found in recent months to have attempted to join ISIS or support the group in other ways. Last month, a 16-year-old accused of planning to join the group was found guilty of illegal possession of a firearm in South Carolina, having been charged with this offense as South Carolina has no anti-terrorism laws.
His conviction followed the arrest of six Somali Americans from Minnesota who allegedly planned to travel to Syria to join ISIS.
In March, California resident Adam Dandach, who tried to travel to Syria last year, was charged with attempting to join ISIS.
A week earlier, three New York residents were arrested for plotting to join ISIS in Syria. One of the suspects had expressed intent to buy a machine gun and shoot police officers and FBI agents if thwarted in his plan to join ISIS.
Comey had revealed last week that authorities had prevented several ISIS-inspired plots to murder Americans on the July 4 Independence Day holiday.
Comey announced that over ten people who were influenced by ISIS's online recruitment campaign were arrested in the last four weeks, reports Reuters.
ISIS-inspired jihadists have attempted a number of attacks in the U.S., but authorities have so far shown great success in reaching the terrorists before their plans get off the ground.
In one case last month, a New York City college student was arrested for plotting a pressure cooker bombing attack in the iconic metropolis.
