Indian police believes serial blasts hatched in Mumbai

Mumbai: Police launched a massive manhunt in India's financial capital on 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 in early July from the suburb of Navi Mumbai, "New Mumbai," police said.

Police were also investigating Kenneth Haywood, a 48-year-old American citizen from California. They seized his computer on Monday after tracing an e-mail claiming responsibility for the attack to the machine.

Authorities have not named Haywood as a suspect and said on Tuesday it was possible the bombers had accessed his wireless network connection to send the e-mail.

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.
