An 18-year-old man was arrested after he posted an “intimate video” of an ex-girlfriend on social media, according to the Anchorage Police Department.

In a release, APD wrote that an investigation into the incident began in February when school resource officers responded to a troubled student. The investigation later revealed the student was upset because her ex-boyfriend, Holden Braund-Nuss, had posted a video of the two of them on social media and sent it to her mother.

Braund-Nuss had also been suicidal, police said.

Police seized both of their cellphones and examined them.

“The examination revealed hundreds of threatening and manipulative text messages from Braund-Nuss to his ex-girlfriend, ultimately resulting in coercion by threatening to post the intimate video on the internet and sending it to her mother if his demands weren’t met,” police wrote.

Braund-Nuss was arrested Thursday at his south Anchorage home. He was charged with harassment and coercion. His bail was set at $5,000 cash, plus a third-party custodian and ordered no contact with the victim.
