ATWATER — A school resource officer subdued a Buhach Colony High student with a Taser on Friday, after police say the student tried to resist arrest.

Police say the incident happened at 10:05 a.m. when a female student reported to officer Matthew Haywood that her boyfriend had assaulted her, according to Atwater police Lt. Sam Joseph.

Joseph said the student showed Haywood her right wrist, which appeared to be swollen and red.

The officer found her boyfriend, also a sophomore about 15 years old, but the boy refused to speak with him.

Haywood told the student he was under arrest, but the student began to walk away.

Haywood placed the student in a reverse wrist lock, but he began pulling away with his left arm and tried to strike the officer with his elbows, Joseph said.

After the officer got the student on the ground, the boy continued to resist and ignored orders to stop. Joseph said the student rolled on his back and began throwing punches at Haywood's head.

The officer rolled the student to his stomach, but he continued resisting arrest, Joseph said. Haywood removed his Taser from its holster and ordered the student to stop and put his hands behind his back.

When the student continued to resist, Haywood applied a single five-second stun application to the student's right lower back area, Joseph said.

According to Joseph, the student continued to roll around, causing the Taser to make several electrical contacts and leave marks on the student's back.

The student then cooperated and was taken into custody, Joseph said. Several Buhach Colony staff members witnessed the altercation and provided statements to police, he added.

The student was taken to juvenile hall and could face charges of assaulting his girlfriend, assaulting a peace officer and resisting arrest.

Haywood did not sustain injuries, although there was damage to his department-issued cell phone, Joseph said.
