Topeka police were investigating a robbery Monday at an eatery on the west edge of downtown.
The holdup was reported about 11 a.m. at the China Express, 514 S.W. 10th.
The robber was said to have been armed with a steak knife. Police said he walked behind the counter and threatened staff before taking an undetermined amount of money from the register.
The man then left the business through a south door.
Authorities said a delivery driver for the restaurant chased the robber but lost him about a block north of the restaurant, near S.W. 9th and Polk. Staff were able to recover the stolen money there.
China Express staff told police the robber was a black man, about 15 to 19 years old, about 5 feet 10 inches tall and weighing 135 to 150 pounds.
He was described as wearing a black coat with a gray hood, black jeans and a black mask.
Two Topeka police officers responded to the restaurant shortly after the robbery was reported. They were joined by a pair of detectives about 11:45 a.m.
Topeka Unified School District 501 police stationed at Topeka High School — a block west of the restaurant — were notified of the incident.
