A top official says that investigators are examining forensic evidence and footage from closed circuit televisions for clues about the triple bomb blasts that shook India's business hub of Mumbai and killed 17.Chief Minister Prithviraj Chavan told CNN-IBN news channel on Friday that investigators had collected evidence such as blood samples and explosive materials from the bombing sites and were also analyzing security footage for more clues into the attacks.
No one has claimed responsibility for Wednesday's attacks and investigators have named no immediate suspects.
The bombings were the worst terror attack in Mumbai since a 2008 siege in which 166 people were killed over three days.
'Mumbai, Thane and other parts of the state are teeming with migrants from Uttar Pradesh, Bihar and illegal Bangladeshis. Unless the government checks the influx of migrants, such acts of terror will not stop,' he said at a press conference here.
Thackeray said the migrants are indulging in all types of criminal activities, ranging from rapes to murders, and many such cases have been exposed in the past few days.
Elaborating on his theory, he said there is absolutely no monitoring of how many migrants come to Mumbai daily, who they are, where they come from, where they live in Mumbai, what is their business and where all they go.
'We have blamed police and intelligence enough in all these years, now it is time to check on the migrants. They come and occupy every vacant space of land belonging to the central, state or civic authorities. 40,000 hutments are constructed on Mumbai's drinking water pipelines. Later, they are pampered as vote-banks and given free flats. What is being done about all this?' Thackeray said.
Demanding a check on each migrant who enters Maharashtra from different entry points, he said that today nobody knows whether the migrants are carrying vegetables or bombs in their baskets.
'They blatantly enter Mumbai, live on railway platforms or footpaths and there is no check on them. After every terror attack, the names of ISI (Pakistan spy agency Inter-Services Intelligence), (terror outfits) LeT (Lashkar-e-Taiba), IM (Indian Mujahideen) and others are thrown up, but who provides them the local logistical support?' he asked.
Thackeray then asked a media person whether he knew where the kitchen of Taj Mahal Hotel is situated. When the media person said he did not, Thackeray said even he did not know - but Kasab, the Pakistani terrorist caught alive in the 28/11 attack, was aware of it.
