Three days after the Kazipara blast killed an eight-year-old boy, chief minister Mamata Banerjee broke her public silence on the incident and said the CID had been asked to probe all aspects of the tragedy and nab those responsible.

In response to a question on Tuesday’s blast, Mamata expressed her confidence in the CID’s capability of investigating it.

“It is a serious matter, a little child died,” she said at a news conference on Friday evening, three days after some senior leaders of her party issued statements accusing the BJP-RSS camp of having engineered the blast.

“The CID has been given charge of the investigation. We expect the CID to look into every aspect and take the accused into custody soon.”

The chief minister’s comment followed a meeting of the core committee of Trinamul at the party’s headquarters. The CID has preliminarily deduced that an eight-inch iron pipe of four-inch diameter and one-mm thickness was used to make the bomb.

Nagerbazar and its neighbourhood, which fall under South Dum Dum Municipality, are among the pocket boroughs of the ruling party.

The locality, however, has witnessed rivalry between Trinamul factions, largely over the supply of construction materials.

The BJP has accused some Trinamul leaders known for their past Naxalite leanings of being responsible for the explosion.

Molest cuffs

A clerk of a private school in Kestopur, off VIP Road, was arrested on Friday for allegedly molesting two six-year-old students.
