Manas Deka, accused by the JNU students leader Kanhaiya Kumar of trying to "strangle" him on board an aircraft in April, on Sunday led a delegation of Assamese youths which greeted BJP president Amit Shah at a function in Pune.
The brief encounter took place before Shah was to address a convention of 'Pramod Mahajan Skill and Entrepreneurship Mission', a state government initiative on the lines of the Centre's 'Skill India', at an auditorium.
However, the delegation did not attend the function and left immediately.
Deka later posted the selfies with Shah on his social media account.
On April 24, Kumar had alleged that Deka, working with a city-based software firm, tried to strangle him on board Pune-bound Jet Airways flight.
Mumbai Police had registered a non cognisable offence on Kumar's complaint. However, the allegations were reportedly described by the police as "untrue".
Kumar had described Deka as a "strong BJP supporter" in his tweet after the incident.
