The US Secret Service investigation into a suspicious network of communication devices in the New York City area came after threatening phone calls were made to two White House aides and a top law enforcement official, according to people familiar with the matter.

The calls, which originated with a network of phone technology through the New York area, spurred the Secret Service to mount the investigation that uncovered the clandestine telecom ring that was revealed on Tuesday.
