Knoxville, TN (WOKI) Two men suspected of robbing a USPS truck Wednesday morning are on the loose.

Knoxville Police Department officials say officers responded around 10:00 a.m. to the 2200 block of Dandridge Avenue when a call came in that a USPS worker had been robbed at gunpoint. They say one of the men had driven away in the USPS truck, while the other had driven away in a white Toyota. The mail carrier was not injured.

About an hour later, officers canvassing the area found the USPS truck and one of the suspects in a vacant lot off of Cityview Avenue. KPD says the armed suspect ran from officers, who eventually lost sight of him in the Chester Avenue area.

Officers were also able to track down the white Toyota, also abandoned on Cityview Avenue. KPD says the suspect may have fled into the area of Walter P. Homes.

Knoxville Police say the efforts remain ongoing to identify and locate the suspects who were described as Black males wearing masks.

Anyone with information that could assist the investigation is urged to contact East Tennessee Valley Crime Stoppers at 865-215-7165. Tipsters can remain anonymous and be eligible to receive a cash reward.
