STONY BROOK, NY — Police arrested a man at Stony Brook University Hospital who allegedly had three explosive devices and an apparent BB gun, officials said.
Robert Roden, a 33-year-old Mastic Beach man who was wearing a tactical vest and has no affiliation with the hospital, was found around 9 p.m. Tuesday, University Police Chief Robert Lenahan said.
"Upon taking the individual into custody, officers observed a suspicious object in his backpack," Lenahan said.
Off-duty NYPD Detective Salvatore Billigmeier happened to be at the hospital when he observed the man arguing with a hospital worker, according to Chief of Detectives Rodney Harrison.
When Roden returned with a backpack, Billigmeier followed him and alerted the SUNY Police department. Roden was subsequently apprehended, and officers retrieved a firearm, multiple 9mm magazines and a suspicious device, Harrison tweeted.
Excellent job by Detective Billigmeier of the 107th Detective Squad for springing into action even when off-duty.
