Westerville police have logged another armed robbery at a South State Street business.

Speedway, 360 S. State St., was robbed by a man with a folding knife at 10:56 p.m. Jan. 28.

According to Westerville police, the man entered the gas station/mini-mart and confronted the lone clerk with a knife, demanding money and cigarettes.

The clerk handed over approximately $144 in cash, and the man took an unknown amount of cigarettes.

The suspect was described as white, between the ages of 20 and 25, between 5-feet-9 and 6-feet tall, and between 145 and 160 pounds. He was wearing a black and gray hooded sweatshirt, gloves and jeans, and had a light-colored bandanna covering his face.

Westerville police, with help from Columbus police, searched the area. A canine unit tracked the man as far as the parking lot of the neighboring Hanby Square shopping plaza, where police said they believe the man had parked his car.

The armed robbery is the fifth of a South State Street business since Nov. 21, when Chipotle, 641 S. State St., was robbed by two people, one of whom had a gun, as employees prepared to close for the evening.

An employee of Deals, 581 S. State St., was robbed at gunpoint of the evening deposits Dec. 23 as he locked the front door of the business. One man committed that robbery while another drove a getaway car.

A single robber displaying a handgun held up the clerk of the BP gas station, 796 S. State St., Jan. 4.

Two men, one of whom had a handgun, entered Yogi's Hoagies, 475 S. State St., at 3:30 p.m. Jan. 14 and demanded money from the 76-year-old owner, who was the only employee working at the time. They made away with more than $1,000 in cash.

Westerville police said previously that investigators believe at least two of the robberies, the ones at Chipotle and Deals, are linked.

All of the robberies remain under investigation.
