One police official told the BBC more than 200,000 people packed the streets to see the team parade through the streets to the stadium but police expected half of that amount.
An official said a stampede occurred when people tried to push through a small gate.
On Thursday, RCB said they would give 1,000,000 rupees (£9,000) to the families of those killed.
“I was never a believer that we need to have roadshows, never,” Gambhir said.
“My heart goes out to the people who lost their lives.
“We need to be responsible. We need to be responsible citizens and responsible in every aspect because every life matters.
“You cannot at any point in time lose 11 people. We can be more responsible.”
