A man has been hailed a hero for saving the lives of motorists by warning them of the large slip that opened up suddenly on the Brynderwyns on Sunday - the only problem is the people he saved don't know whohe is.
Terry Hooper wants to thank the mystery man who "saved lives" but first needs to know who he is so he can pass on his gratitude.
Mr Hooper said the man was standing in the rain under an umbrella, slowing traffic and steering vehicles away from the slip at about 1pm on Sunday.
"If that man hadn't been there, I don't think [he and his travelling companions] would be here. He certainly saved lives," Mr Hooper said.
The underslip, about 20m long in the northbound lane on the south side of the hill, had fallen away leaving an 8m drop to the ground.
