Pakistan-origin US citizen Luqmaan Khan was arrested recently after he was found with an illegal machine gun, as well as a notebook with detailed plans for "urban warfare" and "martyrdom".
According to federal court filings, the 25-year-old, who was a former student at the University of Delaware, was arrested on November 24 after he was found in a vehicle at a park in Delaware after hours, and refused to comply with officers, as per a USA Today report.
Apart from the notebook, the police also found a backpack with a Glock handgun (.357), a machine gun conversion switch (a small device that effectively converts regular handguns into machine guns), and body armour.
When asked about the mentions of martyrdom in the notebook, he allegedly told FBI investigators that martyrdom was "a goal", and "one of the greatest things you can do".
Khan had also written down a target for his attack: an officer from the University of Delaware's campus police force, a map titled 'UD Police Force', and plans to evade police detection if his plans went smoothly.
When FBI officers searched Khan's home, they recovered more firearms, including a scoped rifle, hollow-point pistol rounds, and another handgun converted into a machine gun.
Luqmaan Khan faces federal court charges over the possession of a machine gun and the possession of an unregistered firearm.
In that regard, University of Delaware Interim President Laura Carlson said in a statement that Khan had been separated from the university, and was banned from all university campuses pending his court case, the report added.
The 25-year-old Wilmington resident, said to have moved to the US in his childhood, could be looking at up to ten years in federal prison if convicted.
