Several people were robbed at gunpoint Saturday night as they hung out on the beach directly behind the Fontainebleau, police said.
The Miami Beach Police Department said the group was at the beach shortly before midnight when two men between the ages of 20 and 30 approached them with guns.
One of the men said, "This is a robbery -- give us your phones," while pointing his gun at the victims, police said.
Two of the victims gave their belongings to the thieves, police said, while two others dropped their phones while running for safety. One of the victims also had her wallet stolen.
Police said one of the victims was able to get away, hide under a boardwalk and call 911.
Police said two of the victims in the robbery were juveniles.
Police said one of the thieves was wearing a white hooded sweatshirt that said "Thrasher" on the front and dark pants. The other was wearing a dark-colored hooded sweatshirt, with possible gray striping down the sleeves, and dark long pants.
Police said both men had their hoods pulled down, covering the majority of their faces.
Anyone with information about the robbery can call local law enforcement.
