Last Friday, Daisy was taking a walk near her residence after dinner. While she was walking on the pavement, Arnold, a successful young businessman, was riding his new electric bicycle on the same pavement at high speed. Unfortunately, Daisy was accidentally knocked down by Arnold's electric bicycle which caused her left arm injured although not serious. Some witnesses quickly called 999 and the ambulance and police arrived later.
