Beloit Police are investigating an armed robbery.

According to a Facebook post, officers were called to the Citgo gas station on the 1300 block of Madison Road just before 11:00 Monday night.

A white or Hispanic man wearing black shoes, black shorts, and a dark long sleeve shirt produced a knife and demanded money.

The suspect, who fled on foot, is believed to be the same person who robbed the same gas station on August 5th.

Anyone with information is asked to contact Beloit Crimestoppers.
