Clark County authorities want to find the man who assaulted an officer during a pursuit Sunday night.
Two deputies went to the 2700 block of Dayton Road on the outskirts of Springfield to serve a warrant on Daryl Jackson, 24, who's wanted in an assault case.
The officers stopped a man walking down the street who initially gave a fake name. One of the deputies then recognized Jackson, who then took off running toward nearby woods.
One deputy attempted to stop Jackson with a Taser, but the probes didn't penetrate his thick clothing.
At one point Jackson threw a forearm and knocked down the other deputy, who scraped his knee and pulled a leg muscle.
A K-9 unit was called in but it lost the suspect's tracks in the woods.
The injured deputy was treated at Springfield Regional Medical Center.
Clark Lt. Dusty White said assaults on officers are happening more frequently in his county, and the hunt is on for Jackson who has yet to be apprehended.
"For law enforcement, it's dangerous and I think that that trend will continue," White said.
