CONROE, Texas -

Officials say they have recovered the body of a man who went underwater in Lake Conroe Monday and didn't come back up.

The 30-year-old victim, who has not been identified, reportedly jumped into the water to help a 40-year-old man who showed signs of distress after being knocked off a tube that was being pulled behind a boat.

Officials said the victim made it halfway to the tuber before going under.

The man who fell off the tube was helped out of the water and reportedly suffered minor injuries.

Montgomery County Constables used sonar and divers, along with the North Montgomery County Fire Department rescue boat in the search.

No other details were immediately released.
