A man who struck a Harris County sheriff's deputy during a traffic stop died Monday night after the deputy used a Taser on him, authorities said.

The deputy pulled over the unidentified man's white pickup for a traffic violation about 6 p.m. along the 500 block of Connorvale in northeast Harris County, sheriff's officials said.

The man hit the deputy in the chest and began running after he was told to get out of the pickup. The deputy caught up with him about 75 feet away and used his Taser, sheriff's officials said.

"He (the suspect) fell to the ground and hit his head," said Christina Garza, a sheriff's spokeswoman.

Paramedics were doing CPR on the man while he was taken to Houston Northwest Medical Center. He died at the hospital, officials said.

The deputy also was taken to the hospital to be examined as a precaution because he was hit in the chest and has had past medical issues.

"Our deputy was expected to be OK,“ Garza said.

The incident remains under investigation, officials said.
