Police launched a massive manhunt in India's financial capital Tuesday, believing that the serial blasts that rocked the western Indian city of Ahmadabad over the weekend, killing 45 people, were hatched in a Mumbai suburb.
Four cars used in the weekend bombings were stolen from in the suburb of Navi Mumbai -- "New Mumbai," police said.
Meanwhile, police on Tuesday found 10 unexploded bombs in Surat, a city 280 kilometers (175 miles) south of Ahmadabad, said H.P. Singh, a senior Ahmadabad police officer.
Police defused seven of the bombs and were working on the other three, Singh said. He offered no details on what kind of explosives were found and said the investigation was ongoing.
Authorities were also investigating the computer of an American citizen living there to find out if an e-mail claiming responsibility for the attack was sent from it, or if unknown attackers accessed his wireless Internet connection.
Navi Mumbai police chief Ramrao Wagh told The Associated Press that police have fanned out across the city to find the car thieves. He said all four cars were stolen in early July.
"Once we find the people who stole the cars, it will give us further clues about the blasts," he said.
On Tuesday, Ahmadabad police said that after sifting through the blast scenes it appeared that 22 separate bombs exploded on Saturday, killing 42 people and wounding 183. The death toll was lowered from the 45 originally reported due to several cases being reported twice amid the confusion, said Singh.
Singh said two of the stolen vehicles had been used as car bombs in the attack, while two others had been discovered filled with explosives in Surat, a diamond-polishing hub.
Police issued a sketch of a young man believed to be linked to one of the cars in Surat, Singh said.
Police were also investigating the computers...
