WESTCHESTER - The U.S. Secret Service says it has a man in custody for possibly making alleged threats against President Barack Obama while he visited Westchester on Friday.

Investigators took the unidentified man into custody Friday night in Connecticut, but he has not been formally arrested or charged.

Authorities had said Friday that the man was armed with an assault rifle while passing through Yonkers, reportedly on his way to a fundraiser the president was attending in New Rochelle. It's unclear if he was actually armed.
