For a few air stewardesses, being in an aircraft thousands of feet above the ground was safer than passing through Changi Airport.
That's because a stalker was lurking in the female toilets of the airport, filming women in various stages of undress.
Between November last year and January this year, Guo Jinquan filmed at least three women when they were in the toilet.
Yesterday, Guo, 27, a Singaporean, pleaded guilty to one count of trespassing in a female toilet and one count of insulting a woman's modesty by filming her as she was changing.
Five other charges, including three similar counts of trespass and two similar counts of insulting women's modesty, were taken into consideration.
Guo had been working at Changi Airport's Terminal 1 as an airline's guest services assistant.
On Nov 30 last year, he sneaked into a female toilet on the second storey of Terminal 2 at 6.10pm.
A female cabin crew member had entered the toilet earlier.
He stuck his mobile phone under the door of the cubicle she was in and filmed her before slipping away.
He repeated the act on another female cabin crew member two hours later at the same toilet.
Court papers said he filmed a third woman on Jan 31 around 5am.
He was eventually discovered by a woman in the toilet a quarter of an hour later.
She called the police and Guo was arrested at 6am.
Yesterday, he turned up in court dressed in a checkered shirt, sporting a buzz cut.
His lawyer, Mr Tang King Kai, said in mitigation that Guo had been mentally ill since a young age.
His lawyer said Guo had been hearing voices and seeing ghosts since he was 10 years old.
At the time of his latest offence, Mr Tang said his client was hallucinating and hearing voices.
Mr Tang also said Guo had broken up with his girlfriend in late 2013 and became depressed.
District Judge Liew Thiam Leng called for a further clarification from the psychiatrist before he sentences Guo on Jan 27 next year.
For each charge of criminal trespass, Guo can be jailed up to three months or fined up to $1,500, or both.
For each charge of insulting the modesty of a woman, he faces up to a year in jail, a fine, or both.
