WOODBURY - Police have arrested a Selden mother after she allegedly stabbed her young daughter in the head yesterday in Queens.

NYPD officials say 43-year-old Ann Carimbocas stabbed her 9-year-old daughter, Brianna, in the back of the head four times while visiting friends.

Co-workers of Carimbocas say she was emotionally unstable, but was trying to seek help. Reports say that Carimbocas has been diagnosed with manic depression and has had bouts of stress and anxiety.

Brianna underwent surgery at Jamaica Hospital Center and remains in critical but stable condition.

Carimbocas is charged with attempted murder.
