In the letter, De has claimed that the clashes were perpetrated by "some anti-social elements".
"...while there have been a few stray post-poll clashes in the state perpetrated by some anti-social elements, the law enforcement authorities have been taking firm and appropriate actions in all such cases without any delay," the letter dated June 9 reads.
"The situation is under control and it may not be construed under any circumstance to be a failure on the part of law enforcement machinery of the state to maintain the rule of law and impute confidence among the people," it continued.
Mamata Banerjee-led West Bengal government's statement came after Union Ministry of Home Affairs issued an advisory to the state government expressing "deep concern" over the death of people in a post-poll clash that ensued between BJP and TMC workers.
In the advisory to the state government, MHA has stated: "'It is strongly advised to ensure that all necessary measures are taken to maintain law and order, peace and public tranquillity. It is also requested to take strict action against officials found delinquent in the discharge of their duty."
The clash between the two factions was triggered by the removal of BJP's flag in Sandeshkhali Assembly constituency of North 24 Parganas on Saturday.
State's ruling party, on the other hand, has alleged that a member of their party has also died in the clashes.
