"Extra forces have been called and there will be an increased police presence throughout Mumbai," he said.

Lavish parties on yachts and midnight ferry rides will be missing in 2008, with a heightened alert in place after the Mumbai attackers made their way into the city by boat.

Marine police and the coastguard will patrol the harbour and be in touch with the Navy, which cancelled its Navy Week celebrations and annual ball.

Security is tight in other Indian cities as well, including capital New Delhi where police are locking down popular landmarks such as Connaught Place and the lawns of India Gate after sunset and asking bars and pubs to close by midnight.

Traffic will be regulated in all the major cities and people will be frisked and stopped to check for drink driving.

There would be about 60,000 police on the roads of New Delhi alone, while thousands of them will patrol the streets of Mumbai and Kolkata.

Surveillance cameras and a large number of plainclothes police will be deployed at popular spots in Kolkata, said Shivaji Ghosh, a senior police official.
