A $20,000 bond was set Monday for a Wellston teen who allegedly made threats that prompted a lockdown Friday at Tecumseh High School.

Lucas J. Goss, 18, was being held in the Pottawatomie County Public Safety Center Monday on a complaint of threatening to perform an act of violence; formal charges have not been filed.

Tecumseh Assistant Police Chief J.R. Kidney said the arrest was the result of a situation Friday that prompted a nearly four-hour lockdown of Tecumseh High School.

Kidney said the suspect's reported girlfriend attends Tecumseh High School. The text message reportedly made a threat to the principal, Kidney said, and Goss allegedly made threats to “shoot up the place.”

That message prompted an immediate lockdown about 10:45 a.m. and a search for the suspect. Kidney said based on other information obtained in the investigation, the threats were deemed credible and authorities took no chances.

Kidney, who said Goss resides in Wellston, said they contacted the Lincoln County Sheriff's Office to check his home, then a tip about Goss having ties to Harrah eventually led to him being found.

Kidney said Harrah police located Goss about 2:20 p.m., so the lockdown was lifted by 2:30 p.m.

During the lockdown, Kidney said students were escorted to lunch and everyone else was denied access to the school.

Kidney, who said police have dealt with Goss before, said he previously had another girlfriend at Tecumseh High School.

Case reports will be turned over to the district attorney's office for consideration of any formal charges.
