PA28 pilot on base entry; under tower control; experienced a near midair collision with a cessna in ...

Narrative:

I was on approach to dpa in west chicago; il flying under orders from the control tower. I was asked to report 2 miles northeast on base for runway 28. At about 3 miles northeast of the field the tower request that I squawk identify which I did. At that point the tower cleared me to land on 28. As I continued the base leg; the tower called me out as traffic to a cessna on the right downwind to 28. I don't recall the cessna responding that they had me in sight. Abeam runway 28; I turned right to my final approach (about 1 1/2 miles from the runway) and saw the cessna on right downwind. Between this point and approximately 1 mile from the runway; the cessna; without being instructed to do so by the tower; suddenly turned base; then quickly turned to final right in front of me. I estimate that he was at my altitude; approximately 1;400 ft and only about 200 ft in front of me. (I was able to easily read the tail number and see the pilot in the cockpit!). I immediately slowed down to avoid a collision and pulled up slightly in preparation for a go-around. At this point the tower again asked the cessna if he had me in sight and also confirmed that I was clear to land. I reported to the tower that the cessna cut me off and that I was climbing for a go-around. She (the tower controller) apologized and approved my go-around; called out the traffic I was to follow on right downwind (which I reported as in sight) and eventually landed without incident. While this was close; I never felt in danger of a collision since I had the cessna in sight at all times. I also want to make it as clear as possible that I do not fault the tower controller for this incident. I later called the tower and talked to her about the incident and reiterated that I do not blame her for what happened. She reported that they've had issues with this cessna pilot in the past.
