SAN DIEGO (AP) _ A man with a stun gun hanging from his belt was taken into custody Monday at a campaign rally for Vice President George Bush, the Secret Service and police said.

''Right now it appears there was no danger involved to the vice president,'' said Steve Sergek, the special agent in charge of the San Diego field office of the U.S. Secret Service.

''The person did nothing to present a harm to either the vice president or anyone else there,'' said Sergek.

The gun doesn't shoot any type of projectile and must be touched to a surface to send a charge, Sergek said.

The weapon was tucked in a pouch hanging from the man's belt when a Secret Service agent spotted it, said police Sgt. Nate Caplan.

''They're considered non-lethal but if you had a 75-year old person with a heart condition, it might be different,'' said Caplan.

The man, whose name was not immediately released, was being questioned by the Secret Service, Sergek said. The man was by himself and was not ''anywhere within arm's reach of the vice president.''

''There are indications he has carried the item for self-protection and merely had it with him when he went to the rally,'' he said.

''It may merely have been a situation of very poor judgment. There doesn't appear to be any connection between the item and the visit.''
