Two robberies at knifepoint took place just hours apart in Swindon and both incidents involved teenage suspects targeting electric bikes.

Two teenage boys grabbed a man and demanded that he hand over his electric bike on Friday at around 6pm in a park near May Close.

One of the teenage suspects showed a knife in his waistband and they also forced another victim to give them his Puma backpack.

The victim with the electric bike cycled away in time.

But, in a separate incident earlier that day, a man was stabbed and robbed by a teenager on Frobisher Drive just after 2.30pm.

The victim's electric bike was stolen by a man riding an electric scooter who was wearing a balaclava and dark clothing. He suffered stab wounds which were not thought to be life-changing or life-threatening.

A 17-year-old boy was arrested on suspicion of causing grievous bodily harm with intent in connection with the Frobisher Drive robbery.

Police are now appealing for witnesses to the later incident near May Close involving the two teenage boys.

They are described as white, about 5ft 7in tall with medium build and British accents.

One was wearing a black puffa jacket, black tracksuit trousers and black trainers.

The other was wearing a white t-shirt with a tiger logo, black trousers and black trainers.
