Kolkata, Sep 27 (IANS): Alleging police inaction, senior IPS officer Nazrul Islam Friday filed a petition before a city court seeking investigations against West Bengal Chief Minister Mamata Banerjee and three government officials on a complaint he filed last month.

Islam, an additional director general-rank officer, in his Aug 17 complaint accused Banerjee, Chief Secretary Sanjay Mitra, Home Secretary Basudeb Banerjee and Director General of Police Naparajit Mukherjee of criminal intimidation, causing mental agony, denying him promotion, disallowing leave, bugging communication lines and criminal intimidation of his family members.

"The Hare Street police station before which Islam filed the complaint has refused to investigate the matter. Even the city police commissioner to whom he had written has not taken any action, so we were compelled to file this petition," said Islam's counsel Gulam Mustafa.

"The court today (Friday) admitted our petition and the hearing has begun," said Mustafa, adding that though the complaint was filed over a month ago, police have refused to take any action.
