TEMPE, AZ - With more than 30,000 runners and spectators taking to the streets of Tempe for Pat's Run Saturday, police and participants were on high alert.
Early in the morning, K-9 units could be seen scouring through the parking lots checking cars.
Local law enforcement joined with federal agencies to create a sophisticated security detail.
While details of the security protocols were not released, Sgt. Mike Pooley with Tempe Police said there were a lot more officers on duty.
The extra measures were put in place in response to the Boston bombings.
"We always are scanning the crowds and looking for things," said Sgt. Daniel Macias with ASU Police. Macias often rides a Segway during large events to patrol and make contact with the crowd.
"It can be stressful at times but it is part of the job," he said. He said he feels like people often come up and talk to him about the Segway which helps him make positive contacts with the public.
No problems were reported.
This was the 9th year for Pat's Run. The race honors the memory of Pat Tillman, a former ASU player who gave up a professional football career to serve in the military. He was killed in Afghanistan.
