"Prime minister should concentrate on governance, which is suffering badly under NDA, rather than snooping on opponents," Kejriwal tweeted.
Kejriwal alleged that officials of the Central Bureau of Investigation (CBI) had interrogated Delhi government officials about him.
"Can the prime minister explain this? CBI reports directly to him. What does the PM want?" Kejriwal asked.
He said if Modi wants any information regarding him (Kejriwal), he should set up a team for it.
"PM wants info about me? Let PM set up a team. I will come and answer all their questions. I have nothing to hide," he said.
