"His fans went out of control and started throwing chairs and water bottles at the police," a police official was quoted by news agency as saying.
The police official further said, "Seeing the situation turning out of control, police were left with no option but to lathicharge."
"The fans were angry as Salman did not take part in the marathon. They wanted him to run with them, but seeing the behaviour of the crowd and because of security reasons, the administration decided against it," the official said.
"No one was injured in the incident," he added.
