The victim and his female friend were renovating an upstairs apartment about 6:30 p.m. on April 24 at the intersection of Ebers and Voltaire streets. An unknown suspect parked in the parking lot and started honking his horn and whistling at the victim’s female friend. From the balcony, the victim and suspect got into a verbal argument. The victim told the suspect to leave the property when he challenged him to come down and fight. About an hour later the suspect returned, took a ladder from his truck and climbed up to the balcony. The victim was on his knees scrapping paint off a window when the suspect charged the victim with a knife. The victim fearing for his life hit the suspect with the paint scraper and fell back into the window, breaking the glass cutting the victim. The two fought on the floor and the suspect stabbed the victim in the leg and calf. The victim punched the suspect in the face causing him to become partially unconscious. The victim and female ran to the fire station across the street for help. Officers arrived, and with K-9 took the suspect into custody in the apartment. The weapon used during the incident was recovered at the scene. Both the victim and suspect were transported to the hospital. Their injuries were not life threatening. Area detectives responded to the scene and are investigating.
