Watch 'dangerous' e-motorbikes hurtle through town
Residents of one south Wales town say they feel it is only a matter of time before a death as "dangerous" e-motorbike riders speed through streets.
Some business owners in Tredegar, in Blaenau Gwent, have said they are thinking of leaving because of the problem.
"I don't know my miles per hour but they whizz past here," said restaurant supervisor Michelle Grierson.
Councillor Haydn Trollope added: "I believe somebody's going to get killed."
Gwent Police said it had launched an operation in Blaenau Gwent "to address crime and anti-social behaviour by using a range of tactics and an intelligence-led, targeted approach", and anti-social behaviour had fallen by more than a third.
