Daniel Rye Ottosen, a 26-year-old Danish freelance photographer is believed to be the last Western hostage to be released by the militants alive in June. Ottosen claimed that after his capture, the masked executioner forced him to perform a degrading dance of tango, which would be followed by thorough beatings.

Jihadi John's identity was uncovered by intelligence experts, who revealed him as Mohammed Emwazi, a British citizen of Kuwaiti origin who graduated from Westminster University, according to The Telegraph.

Ottossen recalls being asked by Emwazi, "Do you want to dance?" Emwazi then led him away, supposedly to dance together in a tango dance. Knowing that the humiliating dance would end in a thorough beating, Ottossen claimed that he was too afraid to even make eye contact with the brutal terrorist.

"At that point, I just looked down at the ground the whole time because I did not want to look at them - if you looked them in the eye you would just get beaten even more," said Ottossen.

After enduring the humiliation, threats, and brutal beatings, Ottossen was finally released by ISIS on June 19, 2014, according to The Mirror. His family allegedly paid millions of dollars in ransom for him to be released alive. In one instance, Ottosen claimed to have been tortured for two weeks continually by the militants, who wanted him to confess to being a CIA operative.

He also claimed to have been held with James Foley, an American hostage who later was executed by Emwazi in an execution that appalled the world.
