Teen arrested after threatening Sheboygan high school, second threat in two days

SHEBOYGAN, Wis. (CBS 58) -- For the second day in a row, a teen has been arrested for threatening South High School in Sheboygan. 

A concerned parent noticed an online threat Tuesday and reported it to police who arrested a 16-year-old. 

The incident is separate from a social media threat Monday against the same school in which another 16-year-old was arrested. 

Both threats were found to be not credible. 

School went on as normal Tuesday and school district officials say classes are as scheduled Wednesday.
