The 19-year-old Israeli man accused of making bomb threats to Jewish community center across the United States has now been linked to bomb threats made against centers in Tampa, Orlando and Maitland. 

Michael Ron David Kadar is accused of using a spoofing company to make dozens of threatening calls.

A criminal complaint says Kadar was the one who called Chabad South Orlando the Jewish Academy of Orlando in January to say there were explosives at the facilities. No explosives were found. 

The complaint also says Kadar called the Chabad South Orlando on Jan. 5 and said he was coming to the school with guns to kill dozens of children. The report says he made a similar call to JCC preschools in Tampa. 

Over the next several weeks, the criminal complaint accuses Kadar of making dozens of calls to Jewish facilities across the country and around Florida, reporting bomb threats.

The complaint also says Kadar reported a bomb threat in February at Glenridge Middle School in Orlando, and reported a bomb on a plane at Orlando International Airport. No bombs were ever found.

By using a spoofing company, investigators say Kadar was able to hide his true caller identification, disguise his voice as female and record the calls. They say he also used Bitcoin to pay for the service. 

Kadar was recently arrested in Israel. He has dual citizenship with Israel and the U.S.
