There's new information on what was allegedly found inside the home of a White Plains man accused of using a weapon of mass destruction.

Raymond Elders, 65, faces five charges, including use of a weapon of mass destruction and unlawful manufacture of destructive devices.

Those charges come after a suspected explosive device was found outside an apartment building on Odell Avenue in White Plains Monday, authorities said. Officials later discovered 25 pipe bombs inside Elders' apartment in that building, according to court documents.

In the complaint, officials say Elders denied manufacturing or detonating suspected improvised explosive devices in the vicinity of Odell Avenue.

A man who identified himself as a friend of Elders told law enforcement that he observed Elders assemble multiple explosive devices in the living room of Elders' home. He also said he was aware Elders discusses bomb-making on the internet with others, according to court documents.

Officials allege Monday's incident wasn't the first. Neighbors have heard other explosions in the area over the last several months, as News 12 has previously reported.

There is still no word on a possible motive or explanation behind the alleged incidents.

The president of a security consulting company in New York says the devices found will give more insight into the case going forward.

"A lot can be learned from the devices that are made and the devices they found, how were they put together? You have to work the case almost in reverse," said Sal Lifrieri, president of Protective Countermeasures Inc.

Elders remains in federal custody. He is due back in court at the end of April.
