Montgomery County police say they are investigating a student's threat to Clarksburg High School.

A student posted a threat on Instagram that said, in part, "I can shoot up Clarksburg High School better than Columbine."

The post was later removed.

Police and school officials said the threat is not credible.

Montgomery County Police Capt. Paul Starks said police spoke with the student and the student's father. The student has not been charged, he said.

Starks said the department is taking the threat seriously.

A spokesperson for Montgomery County Public Schools said the student will face disciplinary action and there will be a larger police presence at the school on Monday.
