Ten terrorists leave Karachi, Pakistan in a boat and travel for thirty-eight hours, remaining undetected by the Indian Navy.
Each of the 10 men is given 6 to 7 magazines of 30 rounds each plus 400 rounds not loaded in magazines, 8 hand grenades, one AK-47 assault rifle, an automatic loading revolver, credit cards and a supply of dried fruit.
The terrorists hijack an Indian trawler, the Kuber, killing four fishermen and ordering the captain to sail to India.
They reach within four nautical miles (7 kilometres) of Mumbai and kill the captain. They then proceed to board three inflatable speedboats and proceed towards Colabajetty.
The first boat carrying around ten of them with several large bags docks at Macchimar Nagar, in Mumbai's Cuffe Parade neighbourhood, where six of the men disembark and the rest continue sailing along the shore. When local residents ask about their occupation, the group responds that they are students.
Another such incident plays out in Colaba, when the remaining men come ashore at Badhwar Park, Cuffe Parade. They reportedly tell local Marathi-speaking fishermen to mind their business before they split up and head two different ways.

The terrorists then hijack the jeep and drive away, but are intercepted by a team from the Gamdevi police station near the pedestrian bridge at Girgaum Chowpatty (Coordinates: 18°57′20″N72°48′46″E / 18.955552°N 72.812909°E / 18.955552; 72.812909).
