Héctor Chaves, director of the Bomberos, said that they attend these incidents in the company of police because it is not the first time that the vandals have stoned the units.
But, on Saturday night, they had 16 calls, five of them in Parrita, three in Alajuela, seven in Heredia and one in San Jose. During one of the calls, the crowd started stoning the fire trucks when the firemen tried to put out the flames.
