Social media posts regarding a possible threat to a school in Costa Mesa has led to the arrest of two teenagers, police announced Tuesday morning.
The investigation began about 11:10 p.m. Monday when the Costa Mesa Police Department received reports of a potential threat against Estancia High School, according to a news release from the agency.
One post showed someone apparently holding a rifle with the caption, “Don’t go to school tomorrow,” police officials said. A second indicated there would be a mass shooting at the high school on Thursday.
The posts were shared on various social media websites, according to police.
Detectives began looking into the post and alerted the school’s resource officer, administrators and personnel from the Newport-Mesa Unified School District.
On Tuesday morning, a 17-year-old Estancia High School student was identified by detectives as being responsible for one of the posts, the release stated. She has not been identified.
Investigators also discovered that the original post was allegedly made by 18-year-old Lenny Vega, who is not a student at the school, police said.
He sent the post to others, including the 17-year-old girl, according to the release.
Both have been arrested.
A BB gun air rifle was seized during a search of two homes, detectives said.
“In light of these arrests, there is no credible threat to Estancia High School,” police tweeted Tuesday morning.
Nevertheless, the department plans to increase its presence and police patrols around the campus, which is located at 2323 Placentia Ave., during the school day.
Staff, students and parents have been notified about the incident, which remains under investigation, according to police.
No additional information was immediately provided.
In a separate and unrelated incident Tuesday morning in Orange County, Brookhurst Junior High School in Anaheim was placed on lockdown after reports of an armed individual on the campus, according to the Anaheim Police Department.
A student was found with a fake handgun, and it was determined there was no threat to the school, police tweeted.
The 13-year-old boy has been taken into custody, Anaheim police Sgt. Shane Carringer said.
The Police Department is co-hosting a community meeting with the Anaheim Union High School District to discus the incident. The meeting is scheduled to kick off at 6 p.m. and is being held at 2271 W. Crescent Ave.
