The blast took place in front of the main gate of Madhyamgram High School at 12.57 am on Monday, they said, resulting in the death of one person, identified as Sachiddananda Mishra.
"He was injured and admitted to Barasat Medical College and Hospital. After a surgery, he was taken to a hospital in Kolkata, where he breathed his last this morning," a senior police officer of Barasat Police District said.
The man, in his mid-twenties, had suffered injuries on his left hand, abdomen and upper parts of the left leg, he said.
Forensic experts collected evidence from the spot, while a team from the National Investigation Agency (NIA) also visited the spot and carried out necessary probe into the matter.
Preliminary investigation revealed that the deceased was carrying a black bag, which exploded, he said.
"We have seized torn pieces of the bag. Some wire, two mobile phone numbers, and photocopies of two Aadhaar cards were also found. The mobile phone numbers were of his family members in Uttar Pradesh," he said.
According to the policeman, family members of the deceased claimed that he was working in a glass factory in Haryana and was not in touch with them for an extended period.
