Family members alerted to the manhunt brought Gabriel Mercado, 22, to the Essex County Sheriff's Department in Newark, where Rutherford detectives picked him up, Capt. Patrick Feliciano said.
"He was still wearing clothing with blood on it," Feliciano said.
The victim was in surgery at Hackensack University Medical Center after being slashed and stabbed repeatedly on her face, arms, legs and elbow on Santiago Place near Francisco Avenue, the captain said.
Although severe, the injuries didn't appear life-threatening, he said.
The motive was still unclear: Mercado had worked with the woman but the two didn't have a personal relationship, Feliciano said.
Police were processing Mercado on attempted murder and illegal weapons charges before sending him to the Bergen County Jail.Click here to follow Daily Voice Cliffside Park-Edgewater and receive free news updates.
