Windsor Police are investigating two unrelated robberies, both which took place on Tecumseh Road East.
The latest happened in the 7200 block of Tecumseh Rd. E after a man claimed he had been 'jumped' by two other men at about 4:40 a.m.
When police found the victim he had a bump on his forehead and a scrape on one of his elbows. He was on the pavement in a box store parking lot.
He told police he had been drinking at a bar nearby where he met two other men, they all decided to leave together and cut through the parking lot.
That's when he said the men turned on him. Police said the man's wallet and cash were taken.
Police are checking surveillance video to see if they can get a better picture of what happened.
They are looking for what they're calling two "possible persons of interest in relation to the incident."
