YOUNGSTOWN, Ohio - The investigation into the painting of pro-ISIS messages on the campus of Youngstown State University is active and on-going according to authorities.

As part of the investigation, YSU officials say experts came to the campus Monday to review and help translate the painted messages.

"They indicated they have some inconsistencies of the writing with the true Arabic language and true Arabic writing," said University Relations spokesperson Shannon Tirone.  

YSU says no campus-wide warning was issued immediately on Monday because the FBI determined that there was no validated or credible threat. They say any hint of danger would have prompted a different response.

"We do have a crisis communications plan on this campus, we would have evacuated this campus absolutely immediately," Tirone said.

Although there is no security camera at the rock location, campus authorities are still reviewing video from many other cameras for anything suspicious.

"It's very tedious to look at all of the footage, but it is part of the investigation and and is part of the process," said Tirone. 

It's also been reported that campus police on Monday were called to Cushwa Hall where the word Jihad was found written on a restroom wall.  Police say there was no threatening message, only the word Jihad, and they say there is no way to determine how long the writing may have been there.

At noon on Tuesday a group of students gathered at the rock for a silent rally for peace. Christina Yovick helped organize the rally.

"I though it was very important for our international students on campus and even our veterans to understand that we don't tolerate what was done and that we stand with our students and we support them," Yovick said. 

The university is still asking anyone with information that may help the investigation to call campus police at 330-941-3527, or go to the YSU Police website and provide the information on the anonymous page, which is private and protected.
