Mohandas K. GandhiNEW DELHI, Jan. 20 (AP)-A man who identified himself as a Hindu refugee from the West Punjab exploded a home-made bomb against a wall 50 yards from a place where Mohandas K. Gandhi was addressing an open-air prayer meeting today. No one was injured.

Police said there was no evidence of an attempt upon the life of Gandhi, who was making his first speech since he ended his latest fast for peace.

However, the authorities said the would question the young Hindu. He was seized by members of Gandhi’s congregation. Police said an army-type grenade was found in the man’s pocket but that he had made no attempt to use it.
