Mewat, A beef found in the biryani by the police in Haryana's Mewat as they have been collecting over the past few days. A government lab in Hisar confirmed that most of the biryani samples have beef.

"They (police) are in charge of implementing the law. It is part of their duty to check that beef is not consumed, as it is illegal in India", said, State Minister Anil Vij on Thursday.

On Tuesday, the Chief of Haryana cow welfare Commission, Bhani Ram Mangla, reached Mewat and instructed the police to make sure no beef biryani is sold.

It was claimed by the cow protection body that it has received several complaints that biryani is being served here with chunks of beef.

Bharti Arora, a police officer in the special task force for cow protection, said "The police have been directed to collect samples of biryani from villages where it is being sold and check which meat has been used to prepare it".

For cow slaughter, a person can sentenced to 10 years in jail and for trading in beef, a person can be jailed for five years as cow protection laws are among the toughest in Haryana.
