No violence has been reported Saturday in the Caribbean port city.
Heavily armed police are patrolling in response to a protest Friday that saw people burning tires, barricading streets and throwing things at police. Officers used tear gas and fired shots in the air to disperse the rioters.
Authorities say a 10-year-old died from a gunshot but the source of the bullet is under investigation.
People in the city object to legislation signed in to law Friday that will let export-import businesses buy land they are now leasing in the duty-free zone.
