The television station reported Friday that police took a 28-year-old man into custody Thursday night and found an “arsenal” of weapons at his apartment in Crofton, about 25 miles east of the nation’s capital.
Police said that when they made contact with the suspect, he was wearing a T-shirt reading “Guns don’t kill people. I do.”
The man, identified in media reports as Neil Prescott, was in the process of being terminated from his job at mailroom supplier and document company Pitney Bowes in Prince George’s County and “had made threats directed toward his employer,” according to WJLA-TV.
Police would not confirm the name of the suspect, who is undergoing an emergency mental evaluation.
In last Friday’s shooting in Colorado, 12 people were killed and nearly 60 were wounded. James Holmes, 24, the suspected shooter who allegedly opened fire on the unsuspecting movie theater audience, was arrested on the night of the shooting and is expected to be formally charged Monday.
An official with knowledge of the investigation told The Associated Press that Prescott phoned in a threat to Pitney Bowes that he was going to “shoot the place up.” Investigators say a search of Prescott’s home turned up more than 20 guns, including assault rifles and handguns, and more than 400 rounds of ammunition.
The official spoke on condition of anonymity because the investigation is unfolding.
The official says though the suspect referred to himself as “a joker,” there is no other known connection to the deadly shooting last week at the Colorado movie theater during the latest Batman movie.
A law enforcement source told WJLA-TV that the foiled shooting plot “could have been another Aurora.”
As WRC-TV/NBC4 reports, a search warrant states that Prescott told his employers “I’m gonna load my guns and blow everybody up.”
Pitney Bowes spokeswoman Carol Wallace said in an emailed statement that Prescott was an employee of a subcontractor to the company and had not been on any Pitney Bowes property in more than four months.
The suspect was being held Friday at Anne Arundel Medical Center in Annapolis, where he was undergoing a psychological evaluation.
