A 36-year-old man was charged Tuesday with allegedly attacking three people at random near downtown Los Angeles and slicing one's man ring finger off just two days after he was placed on probation for another assault.

Daryl Barnett faces felony charges of mayhem, assault with a deadly weapon and resisting arrest as well as two counts of assault in connection with the attack, prosecutors said. He is being held in lieu of $265,000 bail.

If convicted he could receive up to 12 years in prison, prosecutors said.

On Saturday, shortly before midnight, Barnett allegedly ran up to a man in the 1400 block of West 37th Street and punched him in the face, knocking him unconscious, authorities said.

A few minutes later, Barnett allegedly punched a woman in the face outside of a house in the 1600 block of West 35th Street, authorities said.

When a man came to the woman's aid, Barnett pulled out a knife and cut off the man's right ring finger, authorities said. When police responded, Barnett allegedly fought with officers before he was taken into custody.

Barnett had been convicted in January of felony battery on a police officer. He was sentenced in that case Thursday to three years probation.
