Agra, Oct 21: Panic gripped devotees gathered at Vishram Ghat along the Yamu river in Mathura for a holy dip on the occasion of “Bhai Dooj” on Saturday as they spotted a strange intruder — a large python — in their midst. Though it did not cause any harm to them, devotees immediately alerted the Forest Department, who in turn informed Wildlife SOS, a conservation non-profit organisation.
