PORTSMOUTH, N.H. — A 25-year-old man seen in a video with a gun in front of a New Hampshire high school threatening a shooting was arrested in Portland on Thursday afternoon, police said.

The Portland Police Department in a release said that 25-year-old Kyle Hendrickson was taken into custody at 164 Washburn Ave. just before 2 p.m. Washburn Avenue is located near Hadlock Field.

Portsmouth Police identified the suspect as Hendrickson. Police did not list a hometown, but said he was known to frequent the New Hampshire seacoast area and southern Maine. Portsmouth police secured an arrest warrant for Hendrickson charging him with criminal threatening with a firearm, a Class B felony.

Police said that Hendrickson will be held in Maine as a fugitive from justice until he can be extradited to New Hampshire.

Portsmouth Police Chief Mark Newport said Hendrickson had not attended Portsmouth High School.

It’s unclear if Hendrickson has an attorney. A phone number for him had been disconnected.


At about 6 p.m. Wednesday, police received a tip about a video showing a man in a vehicle in front of the high school with a gun, according to law enforcement. The message on the video said, “Imma gonna shoot up the school.”

School officials announced they would cancel classes while the investigation continued.

Superintendent Zach McLaughlin said in a message to the community Wednesday that police notified him about the threat and that they would close all seven Portsmouth schools.

“I just want to acknowledge the emotions of a moment like this. It can be laced with fear, anger and sadness,” McLaughlin wrote in a statement posted on social media. “Amid this challenging time, we appreciate your support as we do our best to keep our students and staff safe.”
