"It would have been timely and more credible to the people had he said it then," Mollah, who has been a consistent critic of Bhattacharjee, told reporters here.
Nine innocent villagers were killed in indiscriminate firing from a house owned by a local CPI(M) leader at Netai village in West Midnapore district on January 7, 2011.
Those arrested for the crime were all activists of the CPI(M), the major constituent of the then ruling Left Front.
"Incidents like Netai are wrong. Our boys had done wrong at Netai," Bhattacharjee said, regretting the incident which had created an uproar, at a public rally organised by the Left Front at Midnapore town, headquarter of West Midnapore district.
"It was a grave mistake," he said about the incident.
Mollah, a former minister in the Bhattacharjee cabinet, had on earlier occasions too criticised the veteran leader and some other senior party leaders openly.
