The mob action followed reports that a woman passenger was injured after being allegedly pushed out by a ticket examiner from a Howrah-Midnapore local train.
South Eastern Railways spokesperson Soumitra Mazumdar denied the allegation.
"As the woman jumped from the train on the opposite side of the platform, she received injuries and was rushed to hospital," Mazumdar said.
The situation was brought under control and train service resumed after 65 minutes.
