A 30-year-old man died after the e-scooter he was riding collided with a car in Sharjah on Sunday.
The driver of the vehicle, an Arab man in his 50s, did not stop at the scene.
He was later arrested by police and the case has been referred to the public prosecution.
Sharjah Police received a report of an incident in the emirate's Al Taawun area at about 3pm and said emergency services were immediately sent to the area. The man died at the scene.
Police said the deceased was an Arab man, but did not disclose his nationality.
Police originally said the victim was an 11-year-old child, but they have since clarified that was not the case.
An Emirati boy was critically injured in June 2021 after his electric scooter collided with a car in Khor Fakkan.
Sharjah Police have carried out safety campaigns amid the rising popularity of e-scooters.
The force has warned against the careless use of e-scooters and bikes, and urged riders to wear protective gear.
In March of last year, UAE hospitals reported a spate of injuries from electric scooter accidents.
Doctors say broken bones, bruises and scrapes from falling off the two-wheelers, which can travel at more than 30 kilometres an hour, are common.
