Incident took place in MP's Harda district on Thursday when the couple objected to their luggage being searched.
According to an Indian Express report, "Police said the right-wing activists claimed to have seized "beef" from a bag during the "raid" on the general compartment of the Kushinagar Express on Wednesday before laboratory tests proved it was buffalo meat.
Police have arrested two members of the Samiti - identified as Hemant Rajput and Santosh - who claimed they acted on a tip-off about beef being transported by some passengers."
The victim, 43-year-old Mohammed Hussain said that the incident took place when he and his wife were retunring to their home in Harda district from Hyderabad.
"They pushed my wife around when she objected to our luggage being searched. We live in India and know what is wrong and right, we eat only goat meat. Besides, the black bag from which the meat was seized did not belong to us. Finally, a constable came to our rescue and saved my wife," Hussain was quoted as saying in the daily.
