Income Tax sleuths, who raided the offices and houses of Malayalam super stars Mammootty and Mohan Lal at Chennai, Bangalore, Kochi and Thiruvananthapuram on Friday, have quizzed Mammootty whole last night.

Senior IT officials said they were only looking at mismatches in the IT returns filed and the investments made by them. According to sources, the IT sleuths may also question the other top hero Mohan Lal shortly.

Mammoootty arrived in Kochi around 10 pm on Friday and soon after the IT sleuths started quizzing him. “It continued till 3 am on Saturday,” said family sources.
