Detectives had appealed for information following the attempted hijacking and assault on Tuesday (1 February).
"It was reported just after 8.30pm that two males had attempted to hijack a car in the Hospital Road area of the city," Detective Inspector Johnston said.
"They then assaulted the female owner of the car, punching her to the face, while trying to get the car keys.
"A passer-by intervened before the men made off from the scene. The woman attended hospital for her injuries, which are not believed to be life threatening at this time.
"A 40-year-old man was later arrested on suspicion of attempted hijacking and common assault. He remains in custody, assisting with enquiries at this stage.”
Anyone with further information that they believe could assist the investigation are encouraged to call detectives on their non-emergency number 101, quoting reference 1826 of 31/01/22.
