Washburn High School was placed on lockdown status and most after-school activities were canceled on Tuesday when a suspicious person showed up to inquire about the January doll-hanging incident.

Sgt. William Palmer said that an incident report said the man had a scarf over his face, and attempted to walk past school security personnel at a school entrance. The incident was reported at 10:38 a.m., but the man was gone when police arrived, Palmer said.

The school declared a code yellow alert, meaning that students were kept in classes without passes, doors were locked, and visitors were screened to allow only students and staff into the building.

The school canceled all after-school activities except for a basketball game, and students were asked to go directly home, according to a message the school sent to parents.

The visit followed an incident in which a small group of students were involved in the stringing up of a dark-skinned doll in a school stairway, and a larger group looked on before the school intervened. That incident sparked community indignation and an all-community meeting.
