The incident occurred a day after the team were knocked out of the Copa Argentina by first division side Godoy Cruz.
"After (Thursday's) practice, when we were in the dressing rooms having showers, the barras bravas (hooligans) came into the club with their faces covered and sticks and intimidated us all," Llop said.
"They hit some of the lads," he added.
"When we left, the physical trainer's car and some others had been scratched and the tyres burst. There were eight other cars in that state. They also took money from players," he said.
"There were 150 barras who came into the stadium, broke cars and threatened players," club president Alejandro Nadur said.
Huracan are in eighth place in the second-tier Primera B Nacional standings with 39 points from 29 matches, 20 points behind leaders Rosario Central.
