One of the men also shared images showing a rat covered in gravy.
A chicken curry dinner on Sunday turned out to be a horrifying experience for a customer at a Mumbai restaurant. He discovered that the meat that tasted a little strange was actually a dead rat.
The manager and chef of the restaurant have been charged, the police said on Wednesday.
Anurag Singh and his friend Amin went to an eatery at Bandra for Punjabi food on Sunday night.
They ordered two dishes, one mutton and one chicken-based curry.
When the food arrived, Mr Singh began to eat the chicken curry. But when he chewed into a piece of the meat, he suspected it was not chicken. On closer inspection, he realised that it was a dead rat.
The two men, queasy and outraged, confronted the hotel manager, who "gave vague answers", Mr Singh alleged in his complaint to the police.
He also complained that he felt sick soon after and had to visit a doctor.
The police have registered a case against the hotel's chef, manager and the chicken supplier.
They have been charged with offences like adulteration of food and endangering the life or personal safety of others, the police said.
In a similar incident last month, a Twitter user had claimed that he found a dead rat in a dish served at a famous restaurant in Punjab's Ludhiana. A video showing a dead rat covered in gravy went viral on social media. However, the restaurant denied the video accusing the customer of defaming the establishment.
