Sergio Romo, who saved three of the four games in the San Francisco Giants' sweep of the Detroit Tigers in the 2012 World Series, was handcuffed New Year's Day at the Las Vegas airport after allegedly becoming belligerent with a TSA officer, according to TMZ.com and ABC7.

Law enforcement sources told TMZ Romo was detained after not providing proper ID at an airport security checkpoint. Police handcuffed Romo after he reportedly became "angry and aggressive" and appeared to be under the influence. Officers saw Romo in an "agitated posture" with "clenched fists" and "pacing around," according to ABC7.

Romo, who reportedly was attempting to return to San Francisco after attending a party in Las Vegas, was not allowed to fly and given a misdemeanor citation for violating airport rules before being escorted off airport grounds.

The TSA issued a statement saying:

"...a male passenger was unable to provide identification required of travelers at the TSA Document Control station...airport police noticed the individual engaged in a dispute with a TSA officer and took action."
