Mohammad Ajmal Mohammad Amin Kasab, the only terrorist to have been arrested in connection with the three-day terror attack, shot dead Anti-Terrorism Squad (ATS) chief Hemant Karkare, Mumbai police sources said in Mumbai on Saturday.
They said Kasab, a Pakistani national who was remanded to police custody till December 11, also killed encounter specialist Vijay Salaskar and Additional Commissioner of Police Ashok Kamte.
The sources said ten terrorists had arrived in the city for the first time on the night of Wednesday using the sea route and then dispersed in pairs to the targeted locations.
The terrorists allegedly took taxis to their assigned locations and paid in Indian currency. "Each terrorist was carrying Rs 6,200 with them," a senior police official said.
Kasab was arrested on the night of Wednesday after his partner, whose identity is stated to be Ismail Khan, was shot dead by the police at Girgaum Chowpatty locality in south Mumbai.
Kasab and his partner had first opened fire at CST railway station and then proceeded to Cama hospital and G T Hospital, a senior police official said.
Kasab has allegedly revealed that their plan was to take hostages at the Taj hotel, Oberoi Hotel and Nariman House and then use them to escape from the city, he added.
He said the Indian financial capital was chosen keeping in mind the worldwide impact it would have.
According to a Mumbai crime branch official, the ten terrorists had not come to Mumbai before this to conduct any 'recce' and they had learnt about the locations with the help of Google Earth.
The police are still verifying as to how the blast in suburban Vile Parle and Dockyard Road in south Mumbai was executed and if the terrorist had received help from any local group.
