Teenage thieves terrorrised and robbed an 18-year-old man and his friend as they cycled towards the Asda supermarket in Telford Drive at Cippenham last Wednesday.

The pair had travelled along Wood Lane between 7pm and 7.30pm and turned right on to a path which runs alongside the edge of a field.

As they came to the entrance of the path they were approached by a group of seven teenage boys. One of the group, who was on a bicycle, began to ask the victim questions about his bicycle. He spoke back and continued to cycle while the group member cycled alongside him.

When they reached Telford Drive the offender blocked the victim’s way and began to push him in the chest and grab him around his neck. He then commented to another boy in the group who passed a metal extendable baton to a third boy who held it by his side while the first offender made threats towards the victim.

The victim then got off his bicycle and the offenders stole it. The group of offenders then cycled away towards Wood Lane.

The victim sustained a cut to his finger and a scratch to his elbow during the incident.

The stolen bike is a light blue Carrera Parva model with green lettering on the frame, a black seat and black wheels with a frame number of AA71255966.

The first offender is Asian, aged 17 to 18 years old, of medium build, approximately 5ft 9ins to 5ft 10ins tall, had facial hair and a shaved slit in his eyebrow with dark coloured hair. He was wearing dark coloured tracksuit trousers and was riding a white Carrera bike.

The second offender was aged approximately 12 to 13 years old with a reflective jacket.

The third offender is white, and described as being of chunky build.

No further descriptions of the group are currently available.

Case investigator Jaspal Sahans, of Slough Investigation Hub, said: “This was an understandably distressing incident for the victim during which he was threatened with a weapon by an intimidating group. This is also the fourth bike which he has had stolen this year.

“I would like to appeal for anyone who witnessed the incident to contact police. During the robbery one person walked through the group while they were talking to the victim. I’d like to appeal to this person to come forward and speak to police.”
