State police say it's more likely 21-year-old Michael Miller-Leibowitz, of Alburtis, was under the influence during the incident about 2:45 a.m. Thursday in Upper Milford Township.
Police say the suspect rammed another car three times from behind and then punched the other motorist, who had pulled into a driveway, while shouting that the victim was using heroin. Police say the suspect also had his dog bite the victim.
Police say they twice used stun guns and pepper spray to arrest the suspect on assault, driving under the influence, and other charges. Online court records don't list an attorney for him.
