At least eight people were killed and several injured in a stampede at Haridwar's Mansa Devi temple on Sunday, following a large crowd gathering at the shrine, The Economic Times reported.

The incident took place around 8.30am after a rumoured snapping of an overhead power line, which allegedly fell onto a crowded section of the walkway, triggering panic among pilgrims.

"We received reports of some people being injured, following which the police took immediate action. Around 35 people were brought to the hospital and 6 have been confirmed dead. The rest are undergoing treatment," Haridwar SSP Pramendra Singh Dobal said.

"Prima facie, the stampede was triggered by a rumour of an electric shock on stairs 100 metres down the temple route. We are investigating further," he added, according to The Economic Times.
