A robbery suspect remains at large after he took an undisclosed amount of cash from the Apollo III convenience store, 3011 West Oakland Ave., just before 9 p.m. Monday.

According to Capt. Dave McKichan of the Austin Police Department, the suspect, an older white male wearing a blue face mask, entered the store and told the male store clerk that “This is a robbery.”

He then ordered the clerk to the back of the store and told him to count to a certain number after he took cash from the register, in order to allow the suspect to flee. The clerk reported that he heard the door bell sound and when it did, he ran to the front and contacted authorities.

No weapon was alluded to or seen, the clerk reported, and he did not see a suspect vehicle either before or after the incident. No one else was in the store.

The suspect is described as a male with a medium build, probably in his 50s and 5 foot-8 inches tall. He was wearing dark clothing and a hoodie, tied with its hood up.

Anyone with information is urged to contact the Austin Police Department.
