Crime in Colleyville decreased again this year, dropping to its lowest number in 21 years, city officials said.

The overall decrease from 2011 was 8 percent, including a drop of 44 percent in violent crime; 63 percent in residential burglaries; and 6 percent in overall property crime.

Vehicle burglaries increased by about 10 percent, from 59 to 65.

A Jan. 15 City Council briefing attributes the overall decrease to proactive policing, such as assigning officers to permanent geographic areas to gain expertise, and partnerships with residents.
