STRONGSVILLE, Ohio - Just two days after several Strongsville schools were closed, school officials found another threat of violence.
Strongsville police said they were notified about some graffiti at about 2 p.m. on Wednesday by Strongsville High School officials. The message was written on a stall in a ladies' restroom.
The threat said, "Not a joke. I am bringing guns to school tomorrow. Revenge for getting bullied. You will all pay."
Police said there is no credible information to validate the threat. Officers will be at the school on Thursday.
On Monday, preschools, elementary schools and the high school were closed for a bomb threat. Graffiti was painted on the front of Strongsville High School, including the word "bomb."
