Outgoing City Councilman Hiram Monserrate was arrested early Friday after allegedly whacking his girlfriend over the head with a beer bottle, a police source said.
Monserrate and the unidentified victim arrived at Long Island Jewish Hospital about 4:30 a.m. Sources told the Daily News the woman had severe cuts to her face that required several stitches to close.
Cops later questioned the Queens lawmaker and charged him with assault.
Monserrate was lauded by colleagues just yesterday - his last day serving on the City Council. He's off to Albany after winning an uncontested race for the state senate seat held by former Sen. John Sabini.
The arrest puts Monserrate on an unfamiliar side of the law. He retired from the NYPD in 2000 after a 12-year stint. He's a founding member of the Latino Officers Association and served on the board of the American Civil Liberties Union while still on the police force.
Monserrate has recently drawn scrutiny for a nonprofit called Libre to which he has directed more than $400,000 in city funds that is run by some of its closest aides and has done political work for him.
