When he refuses to apply vermillion to the bride, her relatives are heard saying, "We are only performing your wedding, not hanging you."
Local media quoted the engineer as saying one of the bride's relatives had pointed a pistol at him and ordered him to marry her. His allegations are being investigated by the police.
He told News18, "My brother boarded Hatia-Patna express from Bokaro as he had to attend a wedding function near Patna on December 3. Surendra Yadav, the woman's brother, persuaded him to come to Mokama. He was abducted there and taken to Pandarak where my brother was forced to marry the woman."
However, the cops refused to help, Sanjay alleged.
Then he approached Patna Senior Superintendent of Police Manu Maharaj on whose directions Pandarak police freed Vinod from the village where he was kept after the forced marriage.
"We are looking into it and will take action against the culprits. We are also probing the role of the local police," Patna city SP Amarkesh told News18.
The official figures, as reported by news agency AFP, show police received nearly 3,000 complaints of groom kidnapping in 2016. None of the marriages were annulled.
