The 16-year-old victim, who has been able to give police good descriptions of his attackers, was cycling along Downend Road towards the junction with Shrubbery Road at about 12.45am when he saw three men walking in the opposite direction.
One shouted at him and gave chase. The teenager fell off his bike and was approached by the suspects who threatened him. Two debit cards were stolen from his pocket and the PIN numbers obtained. One was fraudulently used at Martins Newsagents in Downend a short time later.
The victim’s bike, a grey and black Spectrum MTB, was also stolen.
The first suspect is described as black and in his late teens to early 20s, around 5ft 8in and of strong build. He has a pointed chin and thick, hairy eyebrows and is believed to have been wearing a black hooded top which had a blue picture/motif on the back. He was also wearing grey, thick tracksuit bottoms, which had zips on the side, and black lace-up daps.
The second suspect is described as a white and aged between 15 and 16. He was shorter and of big build, with a round face. He is believed to have been wearing thick, grey tracksuit bottoms and a grey hooded top, with the hood up and pulled tightly around his face. It had a black Nike style logo on the front.
It is possible the suspect was wearing braces as the victim believes he saw silver in his mouth.
The third suspect is described as white, skinny, and around 16 years old. He was around 5ft 7in with light brown hair with a fringe to one side. He had a narrow face with a pointed nose and freckles. He wore a black hooded top with the hood up, and jeans. He had a silver chain around his neck.
