HILLSBOROUGH - Investigators have identified the two men seen walking into Hillsborough High School with students Friday, prompting a lockdown.

Police say Nicholas Grande, 20, and Steven Jahn, 19, are charged with trespassing and causing a public nuisance.

The pair was allegedly seen entering the high school Friday morning when students were starting school. School staff called police and put the school on a modified lockdown when they realized the men were seen inside.

Police K-9 units searched inside the school and the parking lot to make sure nothing dangerous was left behind. Students were sent home early. 

No dangerous items were found.

Grande and Jahn were released pending a court appearance.
