In Dyas v. Superior Court (1974) 11 Cal.3d 628, there was testimony that HACLA patrolmen "'are uniformed officers and the vehicles are marked . . . . The uniforms are the color of the marshal's uniforms . . . with the standard basket weave and leather belts, badge and tie, and standard police dress.' He the HACLA patrolman was armed with a revolver, carried handcuffs, and had a two-way radio in his patrol car. Nor did he hesitate to use these indicia of authority in the manner in which they were intended. As we have seen he radioed for a 'back-up unit,' ordered defendant to stand spread eagled against a wall, conducted a pat-down search of defendant's clothing, drew his gun when defendant resisted, arrested and handcuffed defendant on finding contraband, and held him in custody in the patrol car until assistance arrived. Clearly these are the acts of a law enforcement officer." ( Dyas, supra.) The court held that the HACLA patrolman had the duty ". . . to enforce penal statutes and regulations on or about housing authority property, . . ." ( Dyas, supra, at p. 636.)
