A man who an anonymous tipster claimed had pledged his allegiance to ISIS and was planning to shoot police officers in New York and Philadelphia has turned himself in to police, law enforcement sources told NBC 4 New York.
The man turned himself in at a Bronx police precinct Wednesday afternoon and was questioned by detectives, sources said. He was not charged with any crime, but was being held Thursday for allegedly violating his parole.
The NYPD had issued an alert to officers on Wednesday about the anonymous tip called in to a detective squad about a local man who may be armed and prepared to shoot a cop in New York City. Police in Philadelphia also received a similar threat.
According to authorities, the suspect mentioned by the New York City tipster had pledged allegiance to ISIS, NBC New York reports.
