Investigators say a juvenile in Florida is suspected of posting an online threat that there would be a shooting at Derby High School, prompting the district to beef up security for a day.

Officials say the suspect has no connection to Derby High School and it appears the threat was random.

Derby police on Tuesday received a tip that the threat was posted on a gaming website, but it didn’t specify a date.

Classes at Derby High School were held on schedule Wednesday, though additional law enforcement officers were present.

Derby spokeswoman Kristy Bansemer says the FBI helped Derby police identify the suspect on Thursday.

She says the FBI and Florida law enforcement will continue investigating the case.
