It’s exactly what many feared most: A copycat shooter trying to repeat the deadly mass murders in Aurora, Colo.

Police officials have stated that an individual who worked in Prince George’s County, Md., just outside of Washington, D.C., was planning to duplicate the monstrous acts of James Holmes, the man who killed 12 and shot over 50 people during The Dark Knight Rises midnight screening in suburban Denver last week.

This time, would-be murderer’s plans were foiled before it could be perpetrated, WJLA television station reports below:

Authorities in Prince George’s and Anne Arundel counties have foiled what they believe would have been a mass shooting in the style of the one that killed 12 people in a Denver-area movie theater, police sources tell ABC 7 News.

Law enforcement sources tell ABC 7’s Brad Bell that the suspect, who has yet to be identified, was arrested in Crofton on Thursday night. According to officials, the man was facing termination from his job in Prince George’s County.

Authorities say they found an “arsenal” of weapons in his home at the time of his arrest and that he had made threats directed toward his employer.
