Three people have been referred to Youth Aid following the incident, which also included multiple vehicles being stolen in Dunedin and the pursuit of a driver that began in North Otago.
A witness at the scene said the elderly man was physically unharmed but his scooter was damaged, although he was still able to ride it.
