BOULDER COUNTY, Colo. - Classes will resume at Niwot High School this morning with deputies from the Boulder County Sheriff's Office monitoring the school, grounds and neighborhood.
The school was closed Friday after two written threats were found at the school within four days.
"Although the criminal investigation continues, the sheriff’s department recommends that Niwot High open on Monday," said a letter to parents that was posted on Niwot High School's website.
The letter from Principal Dennis Daly explained about the extra police presence, "Additional deputies have been assigned to monitor the school and patrol the grounds and neighborhood."
While no one has been arrested, Daly said one student has been suspended.
"The school district has suspended one student until a number of concerns related to the incident have been resolved," said Daly.
Parents told 7NEWS that a threat to blow up the school was found scrawled on a bathroom wall on Jan. 7.
On Thursday, a second written threat with a hit list of 30 names was found.
Deputies said they have met with the parents of all the students on that list.
The District has not released the name of the student who was suspended.
