A father chained and locked up his 19-year-old son for three weeks for marrying against the family’s wishes in eastern India, a police officer said Friday.

Police rescued Raghu Amin Mollah from his father’s house Thursday on the outskirts of Calcutta, the capital of West Bengal state, said Joy Biswas, a police officer who took part in the operation.

“Yes, he was kept in a room locked and chained,” Biswas told The Associated Press.

The father, Abed Ali Mollah, has been arrested and charged with illegally detaining and torturing his son for 21 days, he said.

Biswas said Abed Ali Mollah opposed his son’s marriage to Shahnaz Khatun, 18, because of enmity between the two families.
