Hillhouse High School in New Haven was on lockdown today after receiving a phone call with a threat that someone was going to come in and shoot a teacher, police said.
Now, police are saying this call is similar to the call that prompted a campus-wide lockdown at Yale last month and they want to speak with the person of interest in that case.
The threat to Hillhouse High came from a payphone at 10:04 a.m., police said.
Police do not believe it is is credible threat to the New Haven High School, but they have responded and said they are taking the every precaution possible.
The lockdown has been lifted and students were dismissed.
Police are looking for possible witnesses and surveillance.
