Police are investigating an online post threatening an acid attack against a high school in Incheon, it said Tuesday. 

They received a report at 10:06 p.m. Monday that a post threatening an acid attack against a high school in Cheonghak-dong, Yeonsu District, had been uploaded online.

Incheon Metropolitan Police arrived at the school at around 6 a.m. on Tuesday, before students began arriving, and patrolled the premises but found no signs of a potential attack.

The Gyeonggi Nambu Provincial Police, which first received the report, plans to track down the person who posted the threat.

"We found no unusual circumstances, and classes are currently proceeding as normal," a police official said Tuesday. "We notified the school of the report and asked it to strengthen its own security measures, including patrols by school security personnel."
