Beachgoers have been warned to let the police know if they see or find any further suspicious bags, or materials on the shoreline, and not to pick anything up.
Tests were run on one single brick found in Paradise Beach Park around 8 am on Tuesday morning.
In a photograph provided by the city, the letters D-I-A-M-A-N-T are visible in black lettering on the package. "The contents field-tested positive for cocaine".More news: Joaquin Phoenix's Joker Won't Cross Over With Robert Pattinson's Batman

Over in Cocoa Beach about 20 miles north, police were also alerted of duffel bag that had washed on to shore.
The collective street value of the 16 bricks found on Paradise and Cocoa Beaches is thought to be around $400,000. In June, $1 billion worth of cocaine was seized on a ship that docked in Philadelphia whose last port of call had been in the island nation, according to NBC News.
In Orlando - the largest nearby city - one kilogram of cocaine has a street value worth approximately $20,000 to $30,000 Dollars ($27,000 to $40,000 CAD), police told NBC.
Police say more suspicious packages might come onshore following the bad weather and are asking beachgoers not to touch them to avoid overdose. "Especially now with these conditions", Hernandez told the newspaper.
