Some unidentified persons exploded crude bombs in four different parts of Kosi Kalan town near here injuring four persons and creating panic.
Large number of police personnel were deployed in the city, which had witnessed communal violence last year in which at least four persons were killed.
"Some unsocial elements threw crude bombs in Bharat Milap Chowk, Sarrafa Bazar, Batasha Bazar and Baldevganj area in an attempt to create panic," said Senior Superintendent of Police R K S Rathore.
Four persons were injured in the attack but they are out of danger, he said.
Two PAC companies and police personnel have been deployed and we will take strict action against those found disturbing peace, the SSP said.
In June last year, four persons were killed and 16 others injured after communal clashes broke out in Kosi Kalan, about 45 km from Mathura, reportedly after a pedestrian used water meant for some religious purpose.
