TAMPA — A 22-year-old man was arrested Thurday after police said he placed several threatening phone calls to his former co-workers at Florida Energy.
How did he do it without being detected for two days?
With the help of an iPhone app, police say.
Noann Najmuddin Najmi used an application called "Caller ID Faker" to alter his cell phone number from being identified and also to alter his voice, authorities said. Najmi, an ex-employee of Florida Energy, made multiple phone calls to various employees at the business over a two-day period.
During the calls, he threatened to blow up the business unless they paid him $1,000, according to police. He threatened to shoot employees who were out in the field unless he was paid and said he would ruin the business with inside information he obtained during his two days of employment
Najmi, of 7822 Capwood Avenue in Temple Terrace, disguised his voice with a modulation device. The threatened employees and police suspected that Najmi was using a smart phone app to alter the caller ID and his voice.
On Thursday night, officers went to Najmi's home in Temple Terrace, where he denied making any of the threatening calls, according to police reports. The officers asked to search his phone, which Najmi allowed, and they discovered the "Caller ID Faker" application. In the notes of the app, it stated that the program's capability was to alter the number that appears on the recipients' caller and that it had the ability to alter the sound of the caller's voice in a variety of ways.
Officers scrolled through the call log and found calls to the business.
Najmi was charged with extortion, threatening to discharge a destructive device, theft of trade secrets and offense against computer users.
