LOS ANGELES (Reuters) - Detectives probing the brutal beating of a San Francisco Giants fan outside Dodger Stadium are examining a video taken in the stands some time before the assault showing him confronted by a man in Dodgers gear, police said on Monday.
The 10-second video clip, shot by an onlooker inside the stadium, shows Giants fan Bryan Stow, 42, sitting in his seat during the Dodgers' Opening Day game on March 31 being accosted by an unidentified man wearing Dodgers blue.
The other man points his finger in Stow's face, and Stow puts his hands up in what appears to be the end of a verbal altercation. The video was made public on Monday with a posting on the celebrity news website TMZ.com.
It was not clear whether the confrontation captured in the video may have led to the attack on Stow after the game in the stadium parking lot, where he was assaulted by two men dressed in Dodgers apparel.
Stow, a paramedic and father of two who had driven to the game in Los Angeles from his home in Santa Cruz, in northern California, was left in a coma from the beating. But doctors last week said he recently opened his eyes and has shown signs of improvement.
Los Angeles police spokeswoman Sergeant Mitzi Grasso said the video seen on TMZ was being examined by investigators as "a piece of the puzzle."
Although the Dodgers fan seen in that video has not been identified, he was definitely not Giovanni Ramirez, the ex-convict named by police as their main suspect in the Stow assault, Grasso said.
A second suspect in the assault remains at large.
Ramirez, whose lawyer says he is innocent, remains held in jail for violating his parole in another case, Grasso said. He has not been formally charged with the beating.
Grasso said TMZ shared the video with Los Angeles police on Friday, three days before TMZ posted the video online. But she said police did not know who took the video because TMZ has declined to reveal its source.
"With something like this, we're going to continue to follow up to see if we can find out the source of the video, and question them to see if they saw anything else," Grasso said. "Our primary suspect is still Giovanni Ramirez."
The beating of Stow, who was wearing Giants gear at the time, touched off a furor in Los Angeles over what critics said was a failure by the city and team officials to provide adequate security.
