NORTH BAY VILLAGE, Fla. (AP) _ A bomb triggered by an ankle-level trip wire exploded outside a television station, killing a man as he walked home from work.

The bomb was attached to a bus shelter at eye level while the trip wire ran just above the sidewalk from the shelter to a hedge, police said today.

``It had a mechanism, some sort of trip wire. An innocent bystander was walking by and he detonated it by hitting the trip wire,'' said Orlando Blanco, an agent of the federal Bureau of Alcohol, Tobacco and Firearms.

The man, who had been walking home from his job as a cook at a nearby restaurant, suffered extensive head and facial wounds and died at the scene, police said. The restaurant identified him as Gouquiang Situ, about 40.

The bomb exploded about 10:30 p.m. Tuesday outside a complex shared by WSVN-TV, the local Fox affiliate, and a number of radio stations. The site is on a small island crossed by a causeway that links Miami Beach and the mainland.

``Something very strange has happened outside our studios here,'' WSVN anchor Rick Sanchez said during the station's late newscast.
