Police in San Diego are looking into what they say isan increased number of rapes involving young women who take part in binge drinking and leave themselves vulnerable to men.
While others crimes in the city have decreased, police say attacks on women who have had too much to drink is one element as to why rapes have increased.
The number of rapes increased by 38 percent during the first six months of 2008 in comparison with the same period last year, from 129 to 178, according to recent crime statistics.
Women also apparently know their attacker in many cases. Stranger rapes are reportedly less than 10 percent of the attacks against women.
