A Hudson Valley school was placed on lockdown after a student reported seeing a man with a gun inside the school.

On Tuesday, a Chester Academy student reported a man with a gun inside the school. There were no reports of shots fired and only the one student reported seeing the man with the gun, according to Town of Chester Police Department.
