The terror attacks in Mumbai revealed deficiencies in law enforcement, especially in the areas of crisis response and management, Ratan Tata, owner of the Taj hotel, which bore the brunt of the carnage, has said.

He also said the hotel had temporarily increased security after being warned of a possible terror attack. But, he said, those measures, which were eased shortly before the terror strikes, could not have prevented gunmen from entering the hotel.

Tata said the terrorists had done a "lot of pre- planning" and that "they seemed to know (the hotel) in the night and in the daytime".

On deficiencies in law enforcement, he said, "we were getting the cooperation that they (authorities) could give us, but the infrastructure was woefully poor".

As an example, the Tata Group Chairman said it took three hours for firefighters to get water to the Taj after a blaze broke out in the oldest part of the 105-year-old building.

"We had people who died being shot through bullet-proof vests", he told a television news channel.

Tata said that not even the army or commandos who ultimately took over the offensive were prepared for the level of organisation and execution that the attackers seemed to have put into their plan.

"They seemed to know (the hotel) in the night or in the daytime," he said referring the terrorists. "They seemed to have planned their moves quite well, and there seem to have been a lot of pre-planning".
