Kanpur, Oct 14 : Blast rocked Kanpur''s Colonelganj area injuring seven people. The injured include three children and a woman.

Initial reports say the bomb was kept on a bicycle in old Kanpur area. Nature of the blast is not known yet. The device was reportedly placed on a rented bicycle.

Kanpur SSP Hari Lal said it is not a terrorist activity. The same is being conveyed to the locals. Loose gravel might have injured, the officer added.

ADG law and order Brij Lal has said that it was a sutli bomb. It was probably being carried on the bicycle, the cracker was disbalanced and the bomb went-off.

The area- situated in the centre of the city- is highly crowded and minority dominated. Several cracker-manufacturing units are located here.

It is a densely populated area, packed with slums in narrow lanes.

The nature of the explosive is not confirmed, but is suspected to be a Diwali cracker as it left the same acrid smell after it went off. The blast was a low-intensity one.

The entire city of Kanpur has been put on high-alert, with the site being cordoned-off. (ANI)
