Kolkata: A group of people "backed by a political party" has put up road blockade in the city's Park Circus area following publication of a photograph in a daily, West Bengal Chief Minister Mamata Banerjee said.

"A photograph was published in a newspaper. An FIR was lodged and the newspaper tendered an apology. But still, those who are obstructing roads with support from a political party I say to them do not play with fire," Banerjee said at the city airport on her return from New Delhi.

She, however, did not name any political party.

Stating that people of West Bengal would not tolerate such action, she said, "I think this photograph should not have been published. This has no relation to either the state government or the state."

"An effort is on to foment communal tension. I am appealing to you with folded hands not to pay heed to rumours and do not get provoked," she said.

Earlier in the day, Banerjee had issued a statement appealing to all for maintaining communal amity and saying the state government would take all steps.

The road blockade in Park Circus and nearby Mullick Bazar areas threw the traffic out of gear for over six hours since afternoon, the police said adding the blockade was lifted late in the night.

No untoward incident was reported.
