The cycle-bomb exploded at a super market complex at Chowpathy in a busy area of the town, the inspector general, north Bengal, K L Tamta told PTI.
Tamta said the bomb was a very powerful one. However, its exact nature was being ascertained. Asked if it could be the handiwork of the United Liberation Front of Asom, he said, "Why should ULFA insurgents come here?"
"Two years ago there was a similar cycle-bomb explosion at Barobisa in the Alipurduar sub-division," the official informed.
Ananth Kumar, the superintendent of police, Jalpaiguri, said some people escaped with minor injuries. The injured have been admitted to a Alipurduar sub-divisional hospital.
Tamta said the area had been cordoned off and a bomb squad has been sent. The deceased has been identified as Sujit Das, 27.
Noticeably, extremists of the Kamtapur Liberation Organisation and the ULFA are active in the area.
