Osceola County deputies arrested a man accused of trying to stop a speeder in his Kissimmee neighborhood by flashing a gun and claiming to be a police officer, reports the Orlando Sentinel. Walter Diolosa, 35, was arrested after a confrontation and charged with impersonating a law enforcement officer and carrying a concealed firearm. According to an arrest report, Taisha Cintron told deputies her brother-in-law was speeding in the neighborhood. She said Diolosa came to her driveway and told them to stop speeding. She told the deputy that Diolosa said, "I'm a cop and you guys can't be speeding, next time I'm gone [sic] write you a ticket," the arrest report said. While Diolosa spoke, Cintron told deputies, he pulled up his shirt and flashed a black gun in his waistband, the report said. Authorities were called. WFTV reports that Diolosa is a Disney worker ¿ not a cop. When investigators checked Diolosa's loaded weapon, they discovered it had been stolen from the Kissimmee Police Department in 1994.
