The Bombay High Court on Friday (September 14) slammed Mumbai Police for arresting cartoonist Aseem Trivedi on "frivolous" grounds and "without application of mind", saying its action breached his freedom of speech and expression. "How can you (police) arrest people on frivolous grounds? You arrest a cartoonist and breach his liberty of freedom of speech and expression," a division bench of justices D Y Chandrachud and Amjad Sayyed said while hearing a PIL filed by lawyer Sanskar Marathe claiming Trivedi's arrest was illegal and unjustified.
