A 26-year-old Harvard extension student is being held without bail for allegedly trying to kill an elderly man at Logan Airport in Boston while naked, the Boston Globe reported.

Prosecutors said on Wednesday that Cameron Shenk went into a woman’s bathroom at the airport on Nov. 22, then took off all of his clothes and climbed into the ceiling. A woman later identified Shenk as the man who fell through the ceiling near the stalls and then ran into a men’s bathroom, where he attacked the 84-year-old victim, biting his ear and trying to choke him with his cane.

“The guy just jumped on me and bit my ear,” the victim told police. “I don’t remember anything else.”

The victim was treated for minor injuries and released on Saturday. State police reportedly needed pepper spray to subdue Shenk, a financial planner by trade studying at Harvard Extension School.

Officials in Suffolk County said Shenk is being held pending the results of a hearing on Monday to determine “whether he is too dangerous to be released on bail.” He was charged with two counts of assault and battery on top of attempted murder, malicious destruction of property and mayhem.

No reason has been given for Shenk’s actions at the airport. His attorney, Francis O’Brien, said Shenk is not mentally ill. But the suspect’s father, Derek Shenk, suggested that the attack was instigated by something substance-related.

“We can learn a lot from Snow White,” Derek Shenk told WBZ-TV. “Sometimes when you’re given an apple, it really does contain poison.”
