Reported by local media:

LOS ANGELES (AP) -- Members of an animal rights group allegedly responsible for vandalizing fast-food restaurants nationwide smashed windows at a McDonald's restaurant in the Harbor Gateway area and scrawled "McKiller" on walls with spray paint. Investigators said the weekend vandalism appeared to be the work of the Animal Liberation Front, which has claimed responsibility for attacks on other fast-food outlets.

"If there is evidence that these people are trying to change societal objectives by the use of force or violence or even property damage, that's our definition of terrorism," police Capt. Gary Williams said Tuesday.

The vandalism at the McDonald's at Carson Street and Denker Avenue occurred about 4:15 a.m. Saturday when the business was closed.

"They threw pieces of brick and concrete at the windows and the drive-through display menu, and they used paint and other markers to spray-paint a variety of messages on there," Capt. Patrick Gannon said. "They used the initials ALF, which has been known as the Animal Liberation Front, on the exterior walls of the restaurant."

There were no telephone contacts for the animal rights organization.

According to the ALF Web site, the organization's members carry out "direct action against animal abuse in the form of rescuing animals and causing financial loss to animal exploiters, usually through the damage and destruction of property."

The ALF's long-term aim, the site said, is to end animal suffering by forcing "animal abuse companies" out of business.
