Mumbai, July 5 -- The city police have registered an FIR (first information report) against activists of the Maharashtra Navnirman Sena (MNS) and detained five people for allegedly vandalising the office of investment analyst, Sushil Kedia, in Worli area today after he was seen in a viral video claiming that he was unable to speak in Marathi despite having lived in Mumbai for over 30 years.

Kedia had also dared MNS to act against him. However, after the incident, he apologied for the same.

The incident was captured on camera, in which five to six supporters of Raj Thackeray can be seen throwing what looked like bricks at the office.

They were seen raising slogans against Kedia and hailing Marathi language and Thackeray.
