A 66-year-old Seaford, Long Island man allegedly shouted death threats and profanities at a group of 5 and 6-year-olds playing sports at an elementary school that bordered his backyard, according to authorities and reports.

Michael Marron allegedly stormed into his yard Thursday evening and screamed, “I will kill you,” along with a string of obscenities at the young children participating in after-school activities at Seaford Harbor Elementary School, according to court documents obtained by Newsday.

His house borders the elementary school, where over 500 students are enrolled.

Marron was arrested Friday and arraigned Saturday at First District court in Hempstead on charges of endangering the welfare and making terroristic threats.

The jarring incident prompted immediate police presence at the school during dismissal and caused outdoor activities to be cancelled. Several students had to be seen by a school psychologist for trauma, officials told the outlet.

Following his arraignment, Marron denied all allegations, telling News12, “I would never do that.”

Marron has had “prior incidents and interactions” with the school community, including a previous arrest for firing a BB gun near the school in 2014, the outlet reported.

Judge Renta Irwin ordered the alleged loudmouth to be released without bail under the condition he submit to of electronic monitoring and stay away from the school.

“He should be away. He shouldn’t be living so close to a school,” Marron’s neighbor, Dean Giamundo, told the outlet.

He will return to court on June 3.
