KPD responded to an assault of a 79-year-old on the Ten Mile Greenway Saturday morning around 8 a.m. The victim was found laying on the trail by a jogger.
KPD said the victim reported he was approaching the Interstate-40 bridge over the greenway when someone attacked him from behind.
The victim was bleeding from several wounds and was taken to University of Tennessee Medical Center for treatment. KPD said his injuries appeared to be non-life threatening.
As of October 4, police were still searching for a suspect in this case.
A release from KPD says that investigators searched the area on foot and with an unmanned aerial vehicle; on Thursday evening, investigators plan to use thermal imagers as the search for a suspect continues.
"If you are in the area of the greenway and observe anyone exhibiting suspicious behavior, please call 911," the release said.
KPD offered several safety tips on the greenway:
Use the greenway during daylight hours, from dusk until dawn only. While on the trails, carry a cellphone in case there is an emergency or if you feel unsafe.
Deputy Chief Patrol Commander Kenny Miller said people should still feel safe.
"We just don’t want people to be too alarmed," Miller said. "Our greenways are very safe. We have a presence on the greenway and we rarely have problems. This is an outlier, but from time to time, those things will happen, and of course we’re investigating to the fullest extent."
Miller said the department conducts about 3000 patrols a year on the city's 124 miles of greenway.
