Hundreds of dead fish were found floating in the Ganga near the temple town of Shukratal, prompting Union minister Sanjeev Balyan to visit the area and demand a probe, police said on Friday.
The fish, which were found dead yesterday, may have died due to toxic industrial effluents in the river discharged by industries in upstream Uttarakhand, a police official said.
Union Minister of State for Water Resources Sanjeev Balyan visited the town yesterday, where devotees throng to see 72-foot idol of Lord Hanuman and take a holy dip in the Ganga. He directed officials to take necessary action against the culprits.
A team has been sent to Uttarakhand to investigate the matter, police added.
