They bundled the groom into the back of the car and sped away as hundreds of guests watched on in horror.
Ashok, a compounder, is understood to have had an affair with a local girl before breaking it off early last year.
His family then set him up with his wife and they got engaged.
When the ex-lover heard he was getting married, she begged him repeatedly not to go through with it and even tried to get his parents to call it off, according to police.
A police official involved in the investigation told the Times of India: ‘The armed men took Ashok at gunpoint and threatened him to accompany them.
‘After bundling him on the rear seat of a car, they sped away,’ a police official said.
He was missing for more than 24 hours before the authorities managed to locate him on Tuesday night.
One of the wedding guests said the abduction happened when the couple were going through their tikka rituals – the branding of the forehead with a red mark.
Deputy Superintendent of Hamirpur Police BK Mishra said they launched a manhunt and got in touch with the groom’s family, but as of yet, no complaint has been filed.
