The police have arrested the man who punched a 69-year-old man along Hougang Avenue 7.
The injured man had been assaulted on May 18 at around 9.30pm.
The man's daughter posted on Facebook for help in identifying her father's assailant.
The woman said that her parents had been crossing the road when the plastic bag her father was carrying "accidentally brushed the man on his helmet" as he tried to avoid the biker.
The man punched her father in the eyes, head and chest and shouted vulgarities at him. He managed to escape despite passers-by giving chase.
The injured man suffered a heart attack after the incident when he was taken to Tan Tock Seng Hospital.
Police said that Ang Mo Kio Police Division officers arrested the suspect, a 62-year-old man, on Saturday.
He will be charged on Monday with committing a negligent act which endangers life or the personal safety of others, police said.
