BAYONNE, New Jersey (WABC) -- Schools reopened in Bayonne, New Jersey, on Tuesday with a strong police presence, officials said.
All schools in the district were closed on Monday after social media posts threatened school shootings.
"The investigation is still on-going, but with the security measures put in place, the Chief of Police, Board of Education President, and I are confident that our schools are safe and we can return to a normal schedule tomorrow (Tuesday)," Superintendent Michael Wanko wrote in a letter.
Officials had identified a tweet posted on Friday threatening shootings at several Bayonne schools and then they found a second threat on Snapchat.
In the interest of student safety, Mayor Jimmy Davis decided that schools should close for the day on Monday "out of an abundance of caution."
