A woman walking on a greenway reported she saw a man holding a knife behind his back while walking behind another woman on Monday, according to KPD.
It happened shortly after 7:30 p.m. on the Jean Teague Greenway near the YMCA on N. Winston Road.
Knoxville police officers say the woman asked the man what he was doing, then he ran westbound toward Gallaher View Road away from N. Winston Road.
Numerous officers, including some on bicycles, saturated the area and talked to witnesses, but they were unable to locate the suspect.
The suspect is described as a white male in his 20s, about 5'10" and 175 pounds with short brown hair. He was wearing a light yellow shirt with khaki shorts.
No one was hurt.
