The family of the San Francisco Giants fan who suffered brain damage after a beating at Dodger Stadium sued the team and owner Frank McCourt on Tuesday, alleging that cutbacks in security and antiquated facilities -- including light fixtures dating from 1962 -- contributed to the brutal attack.

The lawsuit, filed on behalf of paramedic Bryan Stow of Santa Cruz and his two children, contends the team should have provided more security, especially for the high-profile opening day game, after which Stow was assaulted in the parking lot. He remains in critical condition at San Francisco General Hospital.

The suit was filed against a number of Dodger and McCourt entities but did not name Jamie McCourt, who has been fighting with her husband over ownership of the team in divorce proceedings.

Even before the attack, Stow and his three friends were harassed during the March 31 game, with other Dodger fans repeatedly taunting them and throwing peanuts, hot dogs, and wrappers -- “clear signs of intimidation” that Dodger security personnel should have addressed -- the suit alleged.

“The lack of security and inadequate lighting presented a perfect opportunity to commit a variety of crimes,” attorneys wrote in the suit. “Unfortunately, for Bryan Stow, this is exactly what happened.”

A spokesman for the Dodgers declined to comment, saying the team does not discuss pending legal matters. Frank McCourt’s spokesman referred a request for comment to the Dodgers.
