A police team comprising a bomb detection and disposal squad inspected a house at Cherandathur, near Vadakara, where a 26-year-old man sustained serious injuries in a suspected crude bomb explosion on Wednesday night.
The squad recovered firecrackers that were reportedly discarded after collecting gunpowder.
Police sources said the explosion took place when the man tried to make a crude bomb using the collected gunpowder. The youth, who lost his palms in the explosion, is now undergoing treatment at Kozhikode Medical College Hospital.
