A threat received on a student's cell phone prompted a brief lockdown at West Haven High School Monday morning.
School officials said the threat was investigated, and the lockdown was lifted as of 8:15 a.m.
The school resource officer and administrators were notified about the threat a student found on their cell phone.
On Monday afternoon, West Haven police said they arrested 18-year-old Edward McNamara, who they said is allegedly responsible for causing the lockdown.
Police said he reportedly used a blocked phone number and disguised his voice, allegedly saying "don't go to school. We're shooting it up."
McNamara is reportedly enrolled at the school but is currently not attending.
"Its a little frightening. Kind of makes me not want to go to school sometimes. I'd rather just stay home when there is a threat like that. Its like I don't feel safe going to school and that's kind of sad," said Alyssa Singh, a senior at West Haven High School.
He was charged with breach of peace, threatening and harassment.
The school day continued as normal, however there was an increased police and security presence on campus throughout the day.
"The school takes threats seriously and places the safety and security of the entire school community as its top priority," school officials said in a message to parents Monday morning.
The threat didn't stop parents from going to the school to pick up their students.
"I want to have her in my house with me. I mean, I'm scared because of all the things going on, so better to be safe than sorry, I'll take her home for today," said parent Gloria Quiles.
McNamara was held on a $25,000 bond and is expected to appear in court on Tuesday.
