A person familiar with the investigation says the Mets suspended longtime clubhouse manager Charlie Samuels because he's involved in an investigation into illegal gambling by the Queens District Attorney and the New York Police Department.
The team announced the suspension Thursday but did not explain it.
The person, speaking on condition of anonymity because details weren't announced, says MLB believes the alleged gambling involved mostly NFL games.
The person says Major League Baseball security officials became aware of allegations of betting and notified New York City law enforcement.
Samuels was hired by the Mets in 1976 and last month completed his 27th season as clubhouse manager.
In a statement, the team says Samuels was suspended indefinitely last Wednesday without pay.
