A man accused of threatening students at Seaford Harbor Elementary School is scheduled to face a judge on Saturday.

Authorities say Michael Marron yelled terroristic threats and obscenities at children during a sporting event Thursday on the school’s playground.

The incident resulted in calls for a police presence during dismissal that day.

Marron had a past arrest for firing a BB gun near the school, according to authorities.

Parents who spoke to News 12 expressed concern that more incidents could occur.

Police say Marron has been charged with making terroristic threats and endangering the welfare of a child.
