TEWKSBURY — Police in Tewksbury are looking for a suspect who stabbed a driver in an apparent case of road rage.
Dennis Keohane says he and co-worker were headed to work on Wednesday afternoon when another driver started tailgating them on Interstate 93. Keohane says he tapped on his brakes to warn the other driver to back off, but when he got off the highway the other driver followed and yelled at them.
Both men left their cars and the confrontation turned violent. Keohane was stabbed in the head, back and neck. He was treated at a hospital and released later Wednesday.
Police are looking for a dark, late model Honda Civic they think the suspect was driving.
