The following is a summary of this ABC News article:
The FBI has launched a federal terrorism investigation into a weekend stabbing in Roanoke, VA., as it has become apparent that the attacker was trying to behead one of his victims while yelling “Allah Akbar.”
The attacker is a 20 year old man named Wasil Farooqui who has lived in the area. The authorities claim to have been aware of him for some time.
Sources say that he traveled to Turkey and tried to sneak into Syria as an ISIS supporter.
He was arrested on Saturday and is being held on charges of assault with malicious wounding after attacking a man and a woman at an apartment complex with a knife. Authorities believe that he likely picked his victims at random.
Farooqui and his two victims are hospitalized after the attack.
