Kolkata, Expressing shock over the incidents of attack in Ariyadaha in North 24 Parganas district of West Bengal, Governor CV Anand Bose on Wednesday said that the law and order situation in the state has collapsed under the Mamata Banerjee government.

He condemned the incidents in which some people beat up a woman and her son last week, besides the assault on a woman in the same area two years ago, a video clip of which had recently surfaced.

"This is shocking and unimaginable. The video clip shows a dismal picture of contemporary West Bengal. The state government needs to clarify what action it has taken to maintain law and order here," Bose said in a letter to the chief minister. "

CM Mamata Banerjee is also in-charge of the police department.

Bose said, "What is the police minister doing? Why is the minister silent? He should give an explanation."

Police have so far arrested six people, including the main accused, local Trinamool Congress leader Jayant Singh, for their alleged involvement in these cases.
