Christopher Meyer is being treated in a London hospital after he was attacked by two people in a London subway station.
His wife says the 74-year-old Meyer's injuries are "like something you would see in a war zone" after the attack at the Victoria Underground station.
British Police Transport Thursday arrested a 15-year-old girl and a 16-year-old boy on suspicion of causing grievous bodily harm. They have not been identified or charged.
The attack happened Wednesday afternoon. Photos showed Meyer covered in blood in a hospital bed.
Police say the injuries are not believed to be life-threatening.
