Amitabh Bachhan has run into problems with the Income Tax Department once again. This is the first this year but the fourth in a year's time. The taxmen wanted the accounts of how he bought his expensive Ray Ban glasses (worth about 2.7 lakhs). He had used this piece in his movie Zamaanat and later presented it to the director, S Ramanathan. Earlier, the Income Tax had issued three notices to him, asking him to disclose his earnings that the Bollywood superstar had made with his home and overseas projects.
