PITTSFIELD -- The Pittsfield Police officers who traveled to Boston on Thursday are not involved in the manhunt for the remaining suspect in Monday's Boston Marathon bombings.

Police Chief Michael J. Wynn said the four officers who were sent to Boston as part of President Barack Obama's security detail all returned to Pittsfield on Thursday night.

"We don't have anyone in Boston or the surrounding area today," Wynn said this morning.

The four officers -- including a member of the canine unit -- were part of the security detail that protected President Obama when he attended Thursday's interfaith church service to remember Monday's bombing victims at the Cathedral of the Holy Cross in Boston.

"The uniformed officers also assisted with traffic control and perimeter control along the [presidential] motor cade route," Wynn said.

Captain David Granger and Sgt. Mark Trapani provided security from 6 a.m. to noon and officers Darren Derby and James Losaw, the police dog handler, worked a noon to 6 p.m. shift.

On Thursday, the Pittsfield contingnent was charged with guarding two blocks of Tremont Street in downtown Boston, Derby said. The Pittsfield officers were stationed next to officers from Taunton and Revere.

"Where we were stationed everything was normal," Derby said. "There was no disruption."

The president and first lady Michelle Obama flew in from Washington, D.C., on Thurs day morning to join Boston in honoring the three people killed and more than 170 injured as a result of Monday's terrorist attacks near the finish line of the race.

Wynn says the four Pitts field police men volunteered for the duty when the request came from the Massachusetts Major Cities Chiefs Association on Wednesday.

Pittsfield Police officers have participated in the aftermath of terrorism events before. A contingent of officers traveled to New York City following the World Trade Center bombings in September 2001.

Wynn expects the Pittsfield Police Department will incur some overtime costs associated with providing the security detail, a figure he's still calculating. He noted his first priority was meeting the need for mutual aid in Boston.

"If somebody calls for help, we go and we worry about the bookkeeping later," said the police chief.
