Kyle Chris, 39, originally from Iraq, became a naturalized US citizen in 2022 and changed his name to Kyle Najm Chris, according to court documents

An armed man wearing tactical gear walked into a Texas elementary school Tuesday through an improperly closed door and asked about the security presence on campus, authorities said.

Kyle Chris, 39, also known as Muhi Mohanad Najm, was arrested at his home Wednesday night and faces a felony charge of unlawfully carrying a weapon in a prohibited place after the incident at Zwink Elementary School, Fox Houston reported.

Chris, originally from Baghdad, Iraq, became a naturalized U.S. citizen on Aug. 24, 2022 and changed his name to Kyle Najm Chris, according to court documents.

He was arrested at his home, located minutes from the school by Klein Independent School District police.

Chris allegedly told authorities he was a security guard, but was actually unemployed, the report states.

The district said Chris got into the school during a 15-second window when the doors didn’t click shut after a parent left the building. He was wearing what appeared to be a uniform and had a holstered firearm, the district said.

However, the school’s “secure vestibule” system stopped him from going any further by keeping him trapped in the front office area, the district said.

“When the individual was asked by the front office staff to provide identification, he did not provide identification, and the front office staff immediately contacted our armed, full-time campus guard,” the district said in a letter to parents obtained by Fox News Digital.

He left the school grounds and drove away, the district said. No students or staffers were harmed.

Parents were notified of the incident on Wednesday, the district said, because they were working with law enforcement to identify Chris.

“Sending a public notification during that window could have jeopardized those efforts, tipped off the suspect, and delayed the arrest,” the letter states. “Law enforcement had the individual under constant surveillance today, and out of an abundance of caution, additional security measures were in place on campus, including increased police presence.”
