Authorities in the US have rescued a 20-year-old Indian student, who was held captive for months without access to a bathroom, viciously beaten, and forced to work at three homes by his cousin and two other men in an incident described as “absolutely inhumane and unconscionable.”

The victim, whose name was not disclosed, spent months trapped in three homes in the US state of Missouri.

On Wednesday, police descended upon a home on a rural highway in St Charles County. They later arrested Venkatesh R Sattaru, Sravan Varma Penumetcha and Nikhil Verma Penmatsa, and on Thursday charged them with offences including human trafficking, kidnapping and assault.
