Delirious scenes were seen across Kolkata as the city's cricket-crazy crowd went wild in widespread celebration late into the night moments after India's historic World Cup triumph in Mumbai.

No sooner than Mahendra Singh Dhoni hit the winning run off Nuwan Kulasekara for a six-wicket win over Sri Lanka who got past India in an eventful 1996 World Cup semi-finals in Kolkata, euphoric scenes followed across the city.

In a nation where cricket is considered as religion, the triumph by Dhoni's army became the ultimate joy for everybody across Kolkata and India alike.

Thousands of fans wearing Team India jersey waving tricolours flocked to the three-kilometre Park Street stretch, city's most popular address and celebrations continued while similar scenes were seen across the city and elsewhere.

Ganguly might be busy with his TV commentary committments, but the locality of his residence went into the celebration mode as soon as the victory became clear.

With cheers of 'India...India...Vande Mataram... Jai Ho...and De Ghumake...youngsters came out holding tricolors high, a mark of realisation of a billion dreams.

"Many of us were either not born in 1983 or were not grown up to watch Kapil Dev win in the West Indies. We have grown up hearing the Kapil Devil's story from our parents.

"We waited through years, and six editions of World Cups passed by. Sourav Ganguly's team had come to a sniffing distance in 2003. But the moment has come now," 18-year-old Neha Keshri, accompanied by her jubilant friends, said in Behala.

"Celebration has just begun... It will go on and on. We will not stop. We have so far heard the stories now we will celebrate and live on with this moment," said Bijay Dubey, a 33-year-old fan in Tollygunge.

He further said it was the revenge of 1996 semi-final that was etched on his memory after India were declared losers following crowd violence in their clash against eventual winners Sri Lanka at Eden Gardens.

"The scene is still fresh in our minds. We wanted to forget that moment for long and the moment has arrived. Life has come a full circle. We win. Lanka lose," said Dubey.

"The way Dhoni soaked in the pressure and led from the front gives an enormous feeling. We are all proud Indians," he shouted.
