Little League International has stripped Jackie Robinson West of the national title that the Chicago team won last summer after an investigation revealed it had falsified boundaries to field ineligible players.

In a stunning Wednesday announcement that came months after the all-black team, whose ages ranged from 11 to 13 years, captured the attention of the country and the hearts of its hometown, the baseball organization said it also found that after the league had changed the boundaries, some team officials went to surrounding leagues to convince them to go along with what they'd done.

"This is a heartbreaking decision," Stephen D. Keener, the Little League International president and CEO, said in a statement.

"As painful as it is, we feel it is a necessary decision to maintain the integrity of the Little League program. No team can be allowed to attempt to strengthen its team by putting players on their roster that live outside their boundaries."

The team has been suspended from Little League tournament privileges until new leadership is found. The team's manager, Darold Butler, is also suspended, and an administrator from the district that includes Jackie Robinson West has been removed from his position, according to the statement.

The march of the team riveted the city, all the way to its loss in the world championship game to South Korea, and when it was over, thousands of people lined Chicago's streets to catch a glimpse of the boys as they were paraded by bus from their South Side baseball field to a downtown park. There were countless heartwarming stories about the team, including an effort by major league players to contribute money so the parents in the blue collar community could attend the World Series in Williamsport, Pennsylvania, and another about Cubs players huddled around a television watching the team during a rain delay at Wrigley Field. The team was treated to a trip to the major league World Series and to the White House to meet President Barack Obama and the first lady, Michelle Obama.

In October, the organization launched an investigation when a coach from a nearby suburb alleged that Jackie Robinson West had violated rules by poaching top suburban players. The story, which was first reported by DNAinfo.com, appeared to end in December when the national organization said it had uncovered no violations. But the organization said it would reopen the investigation if new information surfaced. About that same time, the organization learned of questions about boundary maps involving multiple leagues, and the investigation resumed.

"Little League International ... learned that Jackie Robinson West Little League knowingly expanded its boundaries to include territory that belonged to other leagues in the district without the approval from the other leagues or the Little League International Charter Committee" and used the "falsified boundary map for their 2014 tournament," the organization said.

League officials did not immediately return calls for comment. Throughout the investigation, the team has maintained that no cheating occurred.

This is the third time in the 68-year history of the Little League World Series that Little League International had vacated wins after an investigation had revealed wrongdoing. In 1992, a team from the Philippines was disqualified and in 2001 a team from the Bronx was disqualified.
