Teens were sent home early from a Delaware County high school on Thursday due to issues with the school's heating system.
Chester High School was dismissed around 10:30 a.m. after parts of the school were left without heat, the school's principal tells NBC10.
Sub-freezing temperatures, hovering in the single digits, were felt across the area Thursday morning as the latest arctic blast hits the area -- making the lack of heat a dangerous issue. There have been four confirmed cold weather deaths in Delaware County over the past two days.
The school is investigating the cause of the issue, but officials believe it is centered around a problem with pipes.
The students were dismissed after being given an early lunch. The principal said officials wanted to make sure the teens ate.
Officials say it is currently unclear whether school will be open on Friday.
