There was an increased police presence at Ludlow High School following a threat made towards the school on an anonymous social media website Thursday morning, according to school officials.
Police arrested 18-year-old Matthew Kertz, of Ludlow, for allegedly making the threat. It does not appear that Kertz is a Ludlow High School graduate.
There is no word yet as to why Kertz made the threat, according to police.
Ludlow Superintendent Todd Gaza told CBS 3 he would have canceled school for the day if he and Ludlow Police Chief Paul Madera thought it was necessary.
A Ludlow High School student saw the threat, which involved a shooting, on the social media website Yik Yak at about 12:30 a.m., police said.
That student contacted the Ludlow Police Department and detectives are now working with Yik Yak to determine who sent the threat. Police said the threat could have been sent from anyone.
Yik Yak is an anonymous gossip app, according to its website.
Several parents could be seen picking up kids from the school Thursday morning. Some parents were concerned information was not sent to them earlier Thursday morning.
CBS 3 has a crew on scene and will bring you updates as they are made available.
