The taxi driver allegedly sped off from traffic lights after they had turned green and ploughed into the birds at a speed of 60km/h. The alleged incident was reported to police by a passerby who was alerted by the sound of a car engine as it accelerated. A veterinarian performed a postmortem examination on the pigeon and determined its cause of death as traumatic shock. Given his job as a professional driver, police described his actions as "highly malicious" – a consideration that prompted them to proceed with the unusual arrest.
