RIDLEY PARK, Pa. - Two military helicopters were vandalized on the production line at a Boeing factory near Philadelphia, the Defense Department said Thursday as it offered a reward.

Federal officials handed out fliers to workers at the Boeing Rotorcraft Systems plant listing a $5,000 reward for information leading to whomever damaged the two H-47 Chinook helicopters.

"We have determined that this was a deliberate act and not an accident," said Ken Maupin, an agent with the Defense Criminal Investigative Service, at a news conference outside the plant.

MILWAUKEE - Ryan Braun grinned.

He had just agreed to the largest contract in Milwaukee Brewers' history.

Braun's contract, which runs through 2015, replaces the $455,000, one-year renewal the Brewers gave him in spring training.
