Lawrence police tased a 54-year-old Lawrence man in the 1000 block of Massachusetts Street on Saturday afternoon after he refused arrest. According to Sgt. Dave Hubbel, the man was acting in a disorderly manner about 1:50 p.m. downtown, swearing and screaming. When an officer responded to the scene, he realized the man already had two warrants for his arrest, Hubbel said. When the officer attempted to arrest the man, the man tried to fight the officer. Several officers responded to the scene, and the man was tased and arrested.
