A cyclist launched a double road rage attack on a motorist – punching him repeatedly before hurling his bike through the windscreen.
The drama happened in Swavesey after the cyclist cut in front of the driver of a blue Subaru Legacy forcing him to brake suddenly.
They had an argument and the cyclist punched the driver and rode off.
The motorist then searched for his attacker through the village and found him 10 minutes later in Market Street.
The road rage incident escalated further and the cyclist used his bike to smash the windscreen.
A police spokeswoman said: “We were called following reports that the cyclist cut out in front of the car which forced the driver to brake suddenly. The driver got out of the car and there was an altercation during which the driver was punched in the face by the cyclist.
“The cyclist rode off and the driver headed to where he believed the cyclist lived. There was a second altercation ten minutes later after the driver spotted the cyclist with another cyclist in Market Street.
“He parked up and again the cyclist punched the man, this time twice. The cyclist also picked up his bike and threw it through the car windscreen. The two cyclists then rode off.”
Police in Cambridge have taken a zero-tolerance approach to aggressive cyclists in the city and surrounding villages by launching a crackdown on anti-social cyclists.
Officers in the city target cyclists who flout traffic laws, including riding without lights, using pavements and running traffic lights.
Police are appealing for information about the attacks in Swavesey which happened between 6pm and 6.16pm on January 4.
The cyclist is described as white, 16-20 years old with short dark hair.
