VALLEJO — A trust fund has been set up for a Vallejo city worker who was beaten and robbed by teenagers Monday, city employee union officials said Thursday.

Street maintenance worker Harold Cabral, 46, was recovering at home Thursday, union officials said.

In Monday's attack, Cabral suffered a fractured skull, fractured jaw, broken teeth and a fractured collarbone, police said. He was treated at Kaiser Permanente, Vallejo Medical Center.

"We are getting a lot of calls and e-mails from the public wanting to know if they can do something," said Frank Caballero, president of the International Brotherhood of Electrical Workers, Local 2376. "We have even gotten calls from the maintenance division of Suisun City (where Cabral lives)." The fund will help pay for costs incurred by Cabral's family from the assault.

Checks can be mailed to: The Harold Cabral Trust Fund, in care of IBEW Local 2376, 111 Amador St., Vallejo, CA 94590.

The incident, captured on video, happened about 3:20 p.m., a half block from Vallejo High School.

Cabral was attacked by several male juveniles and knocked to the ground where he was swarmed by about 40 individuals, police said. Apparently, the incident started when someone threw a rock at Cabral's city-owned back-hoe.

Police said they were working with Vallejo City Unified School District officials to identify witnesses.

It was unclear if the suspects were students.

"We are hoping police can round up these criminals ... we are asking the public or parents that have kids who go to Vallejo High to ask their children to come forward with any information," IBEW vice president Ken Shoemaker said. "We would also like to thank the public for their outpouring of support. We are very thankful for that."
