BRADENTON, Fla. (AP) — Bradenton police will investigate security at schools and officials in Polk County will step up patrols following the deadly shootings Dec. 14 at Sandy Hook Elementary School in Newtown, Conn.

Beginning Tuesday, a team of officers will investigate about a dozen schools within Bradenton’s city limits. Along with the task force, increased patrols of elementary schools will continue.

In Polk County, law enforcement countywide will step up patrols at elementary schools when students return to school Tuesday.

The additional law enforcement and increased patrol will be at no cost to the district.

Hillsborough County has moved to put a higher presence of law enforcement at schools since the Connecticut shooting. Pasco and Pinellas counties have not opted to do the same.
