The death toll from a bomb blast in a New Delhi flower market rose to two on Sunday after a man died from injuries, and investigators hunted for the two motorcycle riders who left the explosive, police said. Another 22 marketgoers were wounded when a package exploded in the Mehrauli area of the Indian capital on Saturday, spokesman Rajan Bhagat told The Associated Press. Investigators questioned several people but have no leads, Bhagat said. «Several people have been detained, questioned and then allowed to go home,» he said. Police were searching for two young people who fled on a motorbike after dropping the bomb concealed in a black package in the middle of a road on Saturday, he said. The package exploded after a teenage boy picked it up and shouted to the motorbike riders that they had dropped it. He died on the spot. A 60-year-old man died overnight in the state-run hospital where the injured were being treated, Bhagat said. No one has claimed responsibility for the low-intensity blast, he said. Sonia Gandhi, the governing Congress party chief, condemned the attack. «The Delhi administration should remain vigilant against such dastardly and gruesome acts of terrorism,» the Press Trust of India news agency quoted Gandhi as saying in a statement.
