Mark Pilgrim from Tilehurst, Berkshire, was the father of two teenage girls
A man has been arrested on suspicion of murder following the death of a man, believed to have been thrown from a car on the M4 in Berkshire.
Mark Pilgrim, 48, from Tilehurst, was hit by a car travelling between Reading and Maidenhead on Friday night.
A 25-year-old man from Tottenham, London, was arrested on Tuesday night.
A post-mortem examination found Mr Pilgrim had multiple injuries to his head and body, consistent with hitting the ground from a vehicle.
A family statement said: "Mark was a loving son, brother and father and his unnecessary and untimely death has left us with a very large gap in our hearts and lives.
"Mark was a very generous man who would give up his time to help out his friends and family.
"He was a real people person who was well known and popular in his local community."
A woman reported striking a man on the motorway while she was driving eastbound between junctions 10 and 8/9 at about 22:00 BST.
Father-of-two Mr Pilgrim was declared dead at the scene by paramedics.
