Frankfurt / Main (dpa / lhe) – A dispute among taxi drivers has escalated in Frankfurt. A 38-year-old parked his taxi outside the designated taxi stands, the police said on Sunday. This circumstance upset a colleague so much that he pulled out pepper spray early on Saturday morning and attacked the 38-year-old with it. The annoyed taxi driver then ran away. The 38-year-old could not see his colleague’s license plate due to eye irritation.
