Lexington police were investigating a robbery in which a man was shot on North Upper Street Monday night.
The victim, who was not identified, suffered a gunshot wound to his thigh that was not life-threatening, said Lt. Eddie Hart of the Lexington police.
Hart said police were flagged down at about 7 p.m. by people who said they saw several people arguing and guns being shot.
Police then found the man who had been shot standing on the sidewalk and leaning against a fence, Hart said.
Never miss a local story.
The man told them he had visited a house on the 600 block of North Upper Street, and when he left, several young men on the porch began to argue with him, then took a black bag he was carrying and shot him.
Hart said officers were questioning seven people inside the house that the man was thought to have visited. He said they also saw a bag inside the house that matched the victim's description of the one taken from him.
Police were getting a search warrant to search the home.
A witness to the shooting and one person inside the house were arrested on unrelated warrants, Hart said.
