Ten terrorists slipped into Mumbai on Wednesday night to carry out attacks but the police are looking out for some local people including a henchman of underworld don Dawood Ibrahim [Images] who could have provided logistics.

The number of militants who entered the city through the sea was 10 and "they are all accounted for," said Joint Commissioner of Mumbai Police (Crime Branch) Rakesh Maria.

He, however, said that they were probing possible local support being extended by some people in the metropolis and "everything would be clear only after investigations".

While nine terrorists had been shot at three locations -- Taj Mahal [Images] and Oberoi-Trident [Images]  hotels and Nariman House -- one Ajmal Amin Kasab was arrested from Chowpatty after a shootout.

Sources, involved in the investigations, said that more blankets had been found in a fishing motor boat that belonged to the fishermen who had been killed by the militants in the high seas while entering Indian waters.

Kasab told interrogators that they were only 10 men and denied any local link, the sources said.

A massive manhunt had been launched to nab a Colaba-based businessman, an alleged henchman of Dawood Ibrahim, who has been designated as Global Terrorist by the US and is suspected to be having links with the al-Qaeda.

He looks after some customs clearing mechanism and also indulges in diesel smuggling for the underworld don, the sources said.

The underworld don's men had also provided a complete picture of the terror targets -- the two hotels and the Chhabad House, which houses the Jewish prayer hall, the sources said.
