Lionel Messi's father, Jorge Messi, was taken to a police station on Thursday night, after a BMW M3 he was driving hit a biker, who was rushed to hospital, the UK Mirror reports.
The unnamed 24-year-old was reportedly left briefly unconscious after the collision at a crossroads in Rosario, Argentina.
An ambulance took the injured man to hospital while police drove Lionel Messi's father to a nearby police station, so they could check his vehicle documents.
He is also thought to been breath-tested before being allowed to leave.
The accident happened around 8pm.
The motorcyclist was left unconscious after being knocked to the ground, but his injuries were categorised as "non-serious", after he was examined by medics in Rosario's Clemente Alvarez Hospital A&E.
The incident is not expected to result in court action.
