Gardai are investigating a bizarre incident in which a 'good Samaritan' claims he was attacked on the M50.
The motorist told gardai that he was savagely assaulted after he went to assist another driver whose car had broken down on the M50.
The incident unfolded at around 3.50am on Sunday when officers at Santry Garda Station were alerted of reports of two men running on the motorway close to the landmark IKEA store.
When officers arrived at the scene, they discovered the 61-year-old man with severe facial injuries.
He was rushed to Beaumont Hospital where it was discovered that he suffered a fractured cheek bone.
According to the account that the man gave gardai, he had been driving on the motorway when he saw a broken-down car.
He approached the vehicle to offer assistance but the driver of the car then attacked him for no reason.
After the assault, the car sped off and gardai arrived at the scene a short time later.
Sources told the Herald that the incident is "highly unusual" and that no arrests have yet been made in the case.
The victim is understood to be a foreign national from an Asian country who has been living in south Dublin for many years.
