NEW YORK - Mayor Michael Bloomberg says that crime across the city is down by 33 percent, putting it on pace to break records for a new historic low.

The mayor gave his mid-year crime update in a weekly radio address Sunday, attributing the drop to smart policing, tough gun laws and heroic work by the men and women of the NYPD.

Bloomberg also reported that murders and shootings are down by 29 percent across the five boroughs.

The Bronx was touted for cleaning up its act. The borough saw 651 murders in 1990, and only 114 last year. This year's murder rates are down an additional 36 percent from last year so far.

The Bronx also has less crime than similarly populated cities. Philadelphia has had nearly four times as many homicides so far this year, and Detroit has seen nearly five times as many murders.
