LOUISVILLE, Ky. (WDRB) -- Police have arrested a Seneca High School student after he allegedly made a statement about a bomb to another student Thursday that led to a brief lockdown.

According to an arrest report, 19-year-old Nevan Lee Swinney was involved in a conversation with another student on March 6 about "making a bomb." Police say Swinney told the other student to "mix gasoline and Styrofoam and cook it."

According to the arrest report, "the conversation led to a student reporting the conversation and causing a lockdown of Seneca High School."

JCPS spokesman Ben Jackey said Thursday that Swinney was searched and no evidence of a bomb was found, but K9 units were called in and the school was placed in a "shelter-in-place/lockdown mode" which he said is standard procedure.

Police say Swinney was cooperative and admitted to making the statements.
