The Times of London Friday said, according to Youth Justice Board figures, girls within that age group committed more than 15,672 individual-based violent crimes last year alone.

In addition, figures indicate that individuals in the young female age group committed 1,000 robberies in 2007 for an average of nearly 45 violent acts daily.

Such figures represented a significant increase among the age and gender group, which committed 47,000 criminal offenses in 2003-04 based on the board's records.

The Times said the figures, officially released Thursday, indicated that girls in the targeted age group committed a total of 59,000 criminal offenses in 2007.

The report of those youth offenses, which range in legal repercussions, prompted the board to call for a study into such criminal activities.

The Times said initial findings of the study have indicated that increased police involvement and the growing number of girls in Britain may be causes for the rising crime rate.
