It was a tough week for parents and students in the Lansingburgh School District in Troy.
There were three social media posts on Tuesday, Wednesday and Thursday, each indicating that something dangerous could happen in Lansingburgh or at the school.
It forced officials to put the school in lockout.
The lockout was lifted on Thursday, after police made contact with the three people that they believe made the three separate social media posts.
The threats were deemed not credible.
