We were operating a revenue flight to DAL. Approaching DAL from the south we were sequenced for a visual approach on a right downwind to runway 13L. As I was turning downwind to base leg the tower advised us that a drone was seen operating on the final approach for runway 13L at approximately 1000 feet and 1 mile from the runway. The tower controller asked if we would be able to sidestep to runway 13R as there was a [law enforcement] helicopter operating on the 13L final searching for the drone. I instructed my First Officer to acknowledge in the affirmative and I maneuvered to land runway 13R and landed without incident.  We did observe the [law enforcement] helicopter but not the drone.
A flight crew on final to DAL Runway 13L were advised of a drone on final at 1;000 feet and sidestepped to 13R. They detected the helicopter investigating the drone; but did not see the drone.
