Tatiana, a ninth grade student from Yekaterinburg, was kicked off of a bus because the wires connected to her heart monitor were protruding from her shirt. The unusual display led one elderly passenger to suspect she might be wearing a bomb, according to local reports. The incident took place on July 29.

Tatiana, who suffers from dystonia, was instructed to wear her monitor on a daily basis. The apparatus allows doctors to monitor her heart’s electric activity through suction cups attached to her chest. The incident occurred while she was traveling home from the hospital, when an elderly bus passenger noticed wires sticking out from her shirt and became suspicious.

“There was an elderly woman sitting beside me. When she saw the wires, she yelled, ‘You are a terrorist! You are going to blow us all up! I will not travel with her,’” the teenager said in an interview.

The driver then decided that either Tatiana or the elderly woman needed to leave the bus, but the older woman categorically refused to leave. Tatiana says she decided to leave the bus herself, as there was another one approaching.

The Sverdlovsk region prosecutor’s office has promised to look into the incident as a failure to “provide adequate services for the transportation of a minor by public transport” and take all necessary measures to remedy the situation, if any misconduct is discovered.
