Police launched a massive manhunt in India's financial capital Tuesday, believing that the serial blasts that rocked the western Indian city of Ahmedabad over the weekend 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. 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. Police issued a sketch of a young man believed to be linked to one of the cars in Surat, Singh said. 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. 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 the nearby city of Surat. A third small unexploded bomb was discovered Tuesday in Surat, a diamond-polishing hub. Police were investigating the computers belonging to Kenneth Haywood, a 48-year-old American citizen from California. They seized his computer Monday after tracing an e-mail claiming responsibility for the attack to the machine. Police said Tuesday that Haywood was not a suspect and it appeared the bombers had accessed his wireless network connection to send the e-mail. “He has never been detained, but we have called on him and questioned him as part of the investigation,” said Parambir Singh, a senior officer in the Anti-Terrorism Squad. “He has said his e-mail ID was hacked and evidence we have gathered shows that his network was used to forward the mail.” Singh said anyone on the two floors below Haywood's 15th floor apartment could have accessed his network. The Hindustan Times newspaper quoted Haywood, a manager at the consultancy company Campbell White, as saying that the telephone technician who set up his Internet connection had insisted he not change his default password. An obscure militant group took credit for the Ahmedabad attack.
