A teenage boy was robbed as he walked along a Biggleswade street.
The 14-year-old was in Palace Street at around 5.15pm on Saturday (November 3) when the incident occurred.
As he passed a group of seven or eight males he was barged in the back and he collided with a wall.
The victim was then patted down by the attacker who took a silver iPod with orange earphones from his pocket before the group fled along Palace Street and the victim ran the opposite way.
The offender was wearing a shiny silver puffa jacket with fur around the hood.
