As reports maintain that women commuters are in large numbers threatened, harassed or otherwise somehow sexually assaulted on the subway, new fears emerge that the system is becoming a magnet for sickos and pervs:

A city transit worker was arrested for sexually abusing a woman in a subway car, police said yesterday.

Bus dispatcher Glenn Jones, 37, was off duty when he allegedly approached a 30-year-old straphanger on the No. 4 train as it rolled into Grand Central station on Saturday afternoon.

Jones rubbed against her buttocks, according to police.
