Two teens wearing black balaclavas pushed an 11 year old girl off her bike and stole it.
Jersey Police say the alleged robbery happened between 6 - 6.30pm on Friday (5 September).
The 11 year old girl had been riding along the cycle track in St Brelade, near Creepy Valley. She suffered an injury to her finger.
The bike was later found damaged.
Officers want to trace two suspects, believed to be boys aged 14 or 15.
Both were dressed in black, with black balaclavas covering their faces. One had blue eyes and the other brown eyes.
They were both wearing Nike trainers - one in Air Max, the other with black Nike 95s.
They had an electric scooter with them.
