The Indians, studying at the Texas A&M University, are in a critical condition. They were rescued from the lake, where they had gone swimming, by a police officer on Saturday.
According to the Bryan police, an officer patrolling the lake was flagged down by a person who said two people swimming in the lake were in distress.
The person who alerted the officer was with the two students, both in their 20s. He had managed to rescue one of them, while the police officer rescued the other one and treated both of them with CPR until medical help arrived, the police said.
It was not immediately clear as to why they were swimming in the severe weather.
