LOUISVILLE, Ky. (WDRB) -- A former Jeffersontown High School student unlawfully entered the building Thursday, causing an evacuation and hurried response from police agencies and district officials.

Louisville Metro Police and Jeffersontown Police responded to the school after a call around 12:30 p.m. Thursday. LMPD Chief Erika Shields said police were informed that someone may have entered the school with a gun.

Jeffersontown Police Chief Rick Sanders told WDRB News the former student, who is 18 years old, was let into the building by a student and was there to confront someone. Sanders said the man told police he didn't have a gun, and no one saw him with a gun. But the school told police some feared he did after he stuck his hand in his pocket during a confrontation. 

He was detained by Jeffersontown Police "a short distance away" from the school. There are no plans to charge the man, Sanders said. Jefferson County Public Schools is now handling the case.

"Our school responded appropriately, and I want to stress everyone is safe here," JCPS spokeswoman Renee Murphy said, noting that crisis counselors will be at the school Friday. "Our staff and our students are all safe this afternoon."

In what appears to be a separate incident, a man was arrested during the evacuation process. As students gathered at the adjacent football field following the evacuation, LMPD said Donald Dorsey, 25, approached the field with a loaded .40 caliber handgun. Police said he "had a slurred speech and smelled of alcoholic beverage." Dorsey admitted to drinking, according to his arrest citation. He was arrested on scene and charged with unlawful possession of a weapon on school property and alcohol intoxication in a public place.

Dorsey's arrest is unrelated to the cause of the initial evacuation.
