Fourteen-year-old is charged with terroristic threats for multiple bomb threats on Kentucky Bridge which shut vital link across Ohio River for hours

A 14-year-old boy has been charged over a number of hoax phone calls which threatened to blow up the John A. Roebling Suspension Bridge which connects Ohio and Kentucky.

The unnamed child is charged with four counts of terroristic threatening, police in Covington, Kentucky, said on Monday.

Several calls were made to 911 earlier this month from an individual who demanded $400,000 and said he would 'kill everyone' and destroy the bridge with pipe bombs. None of the threats were credible.

The first call - on September 13 - closed the bridge for around four hours from 5.30am. Several more calls were made across the following week, sparking more closures.

Lieutenant Justin Bradbury, from Covington Police, said on Monday: 'Following a joint investigation with FBI Joint Terrorism Task Force (JTTF) partners, Covington Police Department and the Boone County Sheriff's Department, an arrest has been made in connection with the four bomb threats made against the John A. Roebling Suspension Bridge.

'A 14 year-old juvenile has been charged in Kenton County with four counts of Terroristic Threatening 1st Degree.

'On Friday, September 22nd, this juvenile was taken into custody in Michigan on an unrelated matter. Because the suspect is a juvenile, we are not able to release any additional identifying information.

'We would like to specifically thank the FBI Louisville/Covington Resident Agency for their hard work and tenacity in bringing the person responsible to justice.

'The partnership we share with this organization continues to prove itself an asset to the city and the region. Thank you for everyone's patience as we worked to ensure the public’s safety following each threat.'

Federal investigators had joined the investigation into the hoaxes after the initial call was made.

During the closures, Covington Police had blocked all vehicle and foot traffic from entering both sides of the Roebling Suspension Bridge between northern Kentucky and Cincinnati.

Sources told Fox19 that during the first call, an individual called authorities, threatening to 'kill everyone if he did not get $400,000' by placing pipe bombs on the bridge.

The anonymous person called Kenton County 911 center at 5.24am, adding that he would 'shoot police' if they pointed guns at him. 

Covington Police later confirmed that the threat was not credible.

More than 9,000 people use the iconic bridge to commute daily. Authorities  were also forced to evacuate dozens of local businesses on either side of the river.

Investigators found nothing when they searched the bridge.

The US Coast Guard shut down all river traffic in the area, with thousands of people affected by the four-hour closure of the bridge.

Authorities investigated if the anonymous threat would affect any other bridges in the area, but only the Roebling Bridge was closed. 

Covington Police Captain Bornhorn told Lex18 that they had 'every agency you can think of' exhausting all resources. 

He confirmed that they were working with the Department of Homeland Security, multiple bomb squads and even drone teams.
