A spokesperson from Frontier Airlines confirms one of its employees has now been suspended from work as a pilot pending investigation for his role in the violent threats made toward Maddie, a seventh grade transgender girl on Facebook posts.

The company says 58-year-old Kevin Bickerstaff was put on indefinite suspension on Monday after the company learned of the situation late Sunday afternoon.

Facebook posts show an account by the same name encouraged other kids at Achille schools to beat Maddie in the bathroom so she would not come back to school.
