Police said two vagrants became involved in an argument on the promenade around 8:45 a.m. between Paso De Playa and Surfer's Point. During the argument, one man allegedly punched the other, causing a deep laceration above the victim's right eye, a broken nose and a possible concussion.
After the two men left the promenade in different directions, police said a bystander called 911 to report that a man who looked seriously injured was at the intersection of Harbor Boulevard and California Street.
The Ventura City Fire Department responded, but the 39-year-old victim refused treatment and fled on foot, according to police. Officers then arrived to the area and found the victim on Harbor near the 101 Freeway.
His injuries were treated at the scene, and then he was taken to Ventura County Medical Center, where he was treated and released a few hours later.
Patrol officers found the suspect near the bus depot on Telegraph Road at about 2:20 p.m., according to police. Christopher Cofield, 24, was arrested without incident and booked at the Ventura County Main Jail on suspicion of battery with serious bodily harm.
