St. Louis police acknowledged assisting with the investigation, but referred other questions to the FBI.

The arrest Friday came just over seven months after Thompson and the New York woman broke up, the criminal complaint says. The two had a relationship, but she ended it, the complaint says.

The woman could not immediately be reached for comment.

The day after the breakup, the executive director of her company received an email from someone claiming to be a producer with a national news organization, claiming that the woman had been pulled over for DUI and was being sued for spreading a sexually transmitted disease, the complaint says.

Over the next few weeks, the woman received texts and emails from a Thompson friend and relative, falsely claiming that he had been robbed, shot and was now dying and was also the victim of a computer hacker who was responsible for her harassment, the complaint says.

For the next several months, the woman, co-workers and a board member of her company received emails that investigators would later trace to Thompson. Some claimed she had an STD. Others threatened to release nude photos of her.

In October, someone falsely reported seeing child porn on the woman’s phone.
