Also in New York City, a call came into The Bronx High School of Science saying a pipe bomb would explode in 20 minutes, a police spokesperson told ABC News. The school was cleared, and it was determined that there was no threat, police said.
The threat seemed to fit the pattern of others deemed not credible, saying that a detonation would occur in the absence of a $20,000 bitcoin payment.
