Police in Samoa have stepped up an operation launched a week ago to stop road racing in different parts of Apia.
They said four suspects have been arrested so far.
The operation followed the death of a 17-year-old boy earlier this month, who was killed in a car accident related to a suspected road race.
The police said they have set up static posts and are patrolling parts of Apia at specific times of the night.
They say social media posts by concerned members of the public could lead to charges being laid against people filmed driving recklessly on Saleufi Road last Saturday
