He challenged that if Kejriwal has any genuine documents then he should hand them over to the government.
"If anybody has done anything wrong law will take its own course," Alvi said.
Kejriwal had alleged on Friday that Congress MP from Unnao, Annu Tandon has a Swiss bank account in which she has illegally stashed Rs. 100 Crore. Tandon had denied the charge.
Asked about his source, Kejriwal had said it was a newly inducted minister in the Union Cabinet.
Alvi said on Saturday that Kejriwal should disclose the name of the leader who revealed the details.
