SAN FRANCISCO — Authorities say they've arrested a suspect in the fatal attack on a 77-year-old newspaper vendor who was an early-morning fixture near a San Francisco BART station.

Police spokesman Carlos Manfredi tells the San Francisco Chronicle ( ) that officers arrested 36-year-old Mark Anthony Cassell on Wednesday after recognizing him from a crime bulletin. Cassell, believed to be a transient, was booked on suspicion of murder.

Investigators say Cassell allegedly lifted Dallas Ayers on Jan. 28 without warning and dropped him to the pavement near Market and Montgomery streets before running away.

Ayers, who had sold Chronicles for three decades, suffered hip injuries and died later at a hospital.

Manfredi said Monday that detectives do not have a motive for the attack.
