A student made a bomb threat towards Stevenson High School in Lincolnshire Wednesday afternoon just a day after another student brought an airsoft gun to the school, police said.

The school resource officers at Stevenson High School responded around 3:55 p.m. Wednesday to a report of a bomb threat made on social media toward the school.

Lincolnshire Deputy Police Chief Kimberly Covelli said officers worked in conjunction with school staff and immediately identified the social media account holder.

A preliminary investigation shows the account holder, a Stevenson High School student, left his cell phone unattended on the school bus.

Another student, or students, got ahold of the phone and used his social media account to send the threat.

The police department said they take these matters seriously and are working with school officials and the bus company to identify the person who sent the message.

Covelli said the investigation so far shows it does not appear the threat is credible.

An extra police presence will be at the school on Thursday to ensure students and staff feel safe.

The incident comes a day after police arrested a student found with an airsoft gun at the school.

School resources officers responded around 12:14 p.m. Tuesday to a report of a student armed with a handgun in the building.

Covelli said additional officers arrived on the scene for assistance and they quickly located a male juvenile matching the description provided by a witness.

The juvenile was detained and searched. Officers found the student in possession of an airsoft gun.

The male juvenile was arrested and petitioned on two counts of disorderly conduct.

He was later released to a guardian following the arrest, Covelli said.
