Entomologist Petr Svacha, who was arrested for allegedly collecting insects from a Darjeeling forest, has to languish in jail. His bail plea could not even be moved because of a lawyers' strike to press for a Gorkhaland state. Czech national Svacha, 51, of the Academy of Sciences, Prague, and Emil Kucera, 52, were held held near Rimbik after forest officers caught them on June 22 with more than 200 beetles, butterflies and moths.
