It seems that a taxi driver was sitting in his cab at around 1 am when a group of intoxicated young men surrounded the vehicle. The taxi driver was unable to drive away and summoned police on his phone. One of the men took off his clothes and began whacking the cab with his belt. After they decided that the vehicle had been sufficiently punished and had learned its lesson, the group left the scene. Police apprehended the belt-swinging suspects a few blocks away.
That cabbie had a good story to tell his wife when he got home. Perhaps he even re-enacted it for her benefit.
