Ardhendu, a former Bombay Dyeing model, who owns a leather business, was born in Mumbai. His father Sailesh Chandra, who died in 1984, was Netaji's younger brother.

Asked if his late father, who stayed in Worli here, was aware that he was being snooped upon, Ardhendu said, "Yes. He told me so."

"The suspicion was there. When the snooping and phone tapping was going on, they (my family members) knew they were being snooped, watched at," he cited.

He (his father) told him that someone told the phone was tapped, Ardhendu said.

"Someone from an intelligence agency had also told him the phone was tapped," a source close to Ardhendu said.

After the INA trials in Delhi, no soldier who served in INA was taken into the Indian Army. The government didn't care for the 20,000-30,000 former INA soldiers," Ardhendu said.
