Hoax caller sparks panic by saying there is a bomb at the Empire State Building - just two days after the Nashville suicide attack

 The New York Police Department responded to a bomb threat at the Empire State Building on Sunday morning that has since been deemed a hoax.  

Someone called 911 just after 11am and told dispatchers a bomb will go off in the iconic landmark at noon.   

Officers from the NYPD's bomb squad responded to the scene but no explosive devices were found inside the skyscraper. 

A spokesperson for the police department told DailyMail.com that the threat 'appears to be unfounded at this time'. 

Police have since deemed the building safe.

NYPD Chief of Department Terence Monahan later tweeted: 'After an investigation by patrol officers, Critical Response and Bomb Squad, at this time there are no credible threats to the Empire State Building.'

No further information is currently available. It's unclear if the call is being investigated further.

The threat comes just two days after a huge explosion rocked Downtown Nashville on Christmas Day. 

The blast, occurring on a mostly deserted street, was prefaced a recording warning those nearby to evacuate.  

Investigators have been searching the home of Anthony Quinn Warner, 63, who has been identified as a person of interest in the bombing. 

Friday's blast emanated from a white RV parked outside the AT&T building on 2nd Avenue at 6.40 am. 

Sources have referred to the incident as a 'suicide bombing' to Fox 17, with evidence suggesting Walker died in the explosion. Three people were also injured and surrounding buildings were severely damaged.

While police have not revealed a motive, Walker is has been described as an 'oddball' who was said to have been paranoid about 5G technology, believing the government was using it to spy on Americans. 

DailyMail.com exclusively revealed that Walker transferred his $160,000 home for free to 29-year-old Michelle Swing just weeks before the blast, which she claims she was unaware of.
