A man has been arrested after allegedly groping three women near a public swimming spot in Cairns.
Police will allege the 24-year-old approached and inappropriately touched the women near the Cairns Lagoon between 12.30 and 1.30pm on Saturday.
A bystander chased him down The Esplanade but he disappeared while running down Spence Street.
However police said they identified the man from CCTV footage and found him soon after.
He is due to face the Cairns Magistrates Court on Monday charged with three counts of sexual assault.
Detectives are appealing for any other possible victims to come forward.
