WHITE PLAINS — Police in White Plains, New York, discovered at least 25 improvised explosive devices inside an apartment early Monday after neighbors reported hearing loud explosions in the area. Raymond Elders was encountered inside the apartment and arrested, and he now faces multiple federal charges in connection with the discovery of the devices.

According to a criminal complaint, neighbors called police after hearing loud explosions coming from the vicinity of the residential building. At least one neighbor reported that the blasts had been occurring in the area for several weeks before authorities were contacted. Reports of the loud booms in the suburban New York neighborhood led authorities to the apartment where the devices were found.

When officers arrived at the scene in White Plains, a witness directed them to the specific building where Elders lives. As an officer approached the front steps of the building, the officer noticed an acrid, burning odor in the air, the criminal complaint stated. The responding officer also spotted what was believed to be a pipe bomb sitting on the front steps of the building, prompting further investigation of the premises.

Officers entered the apartment and found Elders and another person inside, according to the criminal complaint. Elders was holding a lighter when police encountered him and had bluish black chemical residue on his hands. Authorities conducting a search of the residence then discovered the stockpile of at least 25 improvised explosive devices within the apartment.

Prosecutors cited surveillance video from earlier this month that showed a man believed to be Elders standing on a sidewalk on his street holding what appeared to be an explosive device. The footage showed the man light the device, throw it into the street, and then flee on foot. An explosion was recorded on the video seconds after the device was thrown, prosecutors said.

Elders faces charges including using a weapon of mass destruction, manufacturing destructive devices, and possessing destructive devices and explosives after felony convictions, according to court filings.

Elders made his initial court appearance on Tuesday. A judge ordered that he remain in federal custody, noting that Elders was a potential flight risk and a danger to the community.
