Airplane Molester Gets Jail and Cane in Singapore
SINGAPORE, Jan 31 (Reuters) - An Indian man faces three strokes of the cane and a year in a Singapore jail after being convicted of groping a woman on an airplane while she slept.
Swarup Das's claim that he was asleep when he accidentally touched the woman was dismissed by Judge Hoo Sheau Peng as "hard to believe," the Straits Times newspaper reported on Wednesday.
The 27-year-old computer engineer was seated beside the woman on a Singapore Airlines flight from San Francisco to Singapore on September 8 last year.
The woman covered herself with a blanket before dozing off, but was awakened by Das's right hand resting on her groin.
She pushed his hand back thinking it was an accident, only to be woken 30 minutes later when she felt his fingers slipping into her underwear. She flung his hand away and informed the cabin crew of the incident.
Das was sentenced on Tuesday and was appealing against it. The court was not immediately available for comment.
