Blood was spotted at the ground near HAL township this morning, but we did not find any carcass there, Circle officer Cantonment police station Pavitra Mohan Tripathi said.
Alleging that a cow was slaughtered in the area, locals blocked the Ramdevi Road, he said, adding the blockade was lifted after police assured them of a detailed investigation into the incident.
A probe is underway to see whether a cow was indeed slaughtered or this was an conspiracy by radical elements to flare up communal tension in the city, police said.
A case has been registered in this connection against unidentified persons, Tripathi said.
