Japanese women are overcoming their usual shyness to tackle gropers on crowded trains. Many have begun to catch perverts and turn them over to police or railway workers at stations. The number of cases in which men were detained for questioning on suspicion of molesting women has increased since the Tokyo Metropolitan Police Department opened a counter in July last year to deal with grievances, police said. There were 162 such cases in 1995, about the same level as in previous years. But police said the number jumped to 219 last year, mainly because women are willing to resist unwelcome advances. A woman in her 20s snatched the company badge from a groper's suit when he touched her body on a train in August, police said. The man grudgingly followed her to the police because he concluded that they would trace him through the badge's identity number. He was later arrested. Another woman in her early 20s turned a man in to the police, and was not daunted when he protested his innocence. 'I scratched his hand,' the woman said. Police found a red welt on the back of his hand and took it as proof that he had molested her. Gropers can be arrested on suspicion of violating a Tokyo ordinance that bans conduct causing trouble to others, and on more serious charges. Police say the rise in the number of men taken in for questioning in connection with groping on trains is attributable to several factors. It helps to have officers patrolling in plain clothes to assist women who wish to lay a complaint, and officers can also arrest men in the act of assault, police said.
