Lazaridis is also RIM's President and Co-CEO.

While appearing in an interview on BBC, he said the whole question about the security concern was "unfair" and the company was being singled out.

Asked again about the concerns and whether the issue is being sorted out, Lazaridis said, "We are dealing with so many issues. We are trying our best to deal with the expectations...."

Upset by the questions repeatedly, he abruptly finished the interview and said "Interview was over".

BlackBerry has been facing security concerns in India, with the Ministry of Home Affairs asking telecom operators to either provide monitoring facility to enforcement agencies or stop offering services.

With nearly a million BlackBerry subscribers, India is emerging as one of the fastest growing markets for Canada-based RIM.

The company has been maintaining that it was an industry issue and it should not be singled out. Like BlackBerry, other Internet-based services such as Gmail and Skype too were offering similar technology platforms.

The government had, however, said the company need to place its server in India to ensure that security agencies get access to the BlackBerry Enterprise Mail services.
