A Sikh priest was among three persons injured when an explosion ripped through a gurudwara in Germany's western city of Essen.
The two allegedly detonated a fire extinguisher filled with explosives at the entrance of the Nanaksar Satsang Sabha Gurdwara on the evening of April 16.
A special commission has been set up by Germany's western city of Essen for a thorough probe into the gurdwara explosion.
