The incident marked yet another strange turn in a cat-and-mouse game that became a tabloid sensation in New York City. Braunstein had tormented authorities for weeks by popping up in various public places; there were reports of him all around New York City, in bars in Ohio and at a blood bank in Memphis.

In investigators said they believe Braunstein was obsessed with the victim and wanted to question him about the attack by a man who bluffed his way into her apartment after setting two small fires and pounding on her door while dressed in full fire gear.

A $12,000 reward had been offered for information leading to Braunstein's arrest and his father had made several public appeals, begging his son to turn himself in.

"Just goes to show you how desperate he must have been," Braunstein's father, Alberto Braunstein, told MSNBC on Friday night. "As a father, I'm terribly saddened. And I hope that now the news will cover something else, because you would have thought that he murdered 20 people."

Police said Braunstein, who is charged with one count of aggravated assault in Memphis, threatened the campus officer out a dagger and a BB gun.
