A Florida man is dead after being repeatedly shocked by a Taser stun gun.

Police say 45-year-old Kenneth Oliver of Miami-Dade showed up at a friend's home early Friday morning, shouting and banging on the front door.

The friend, Johnnie Mosely, told police he considered letting Oliver in, but his daughters were frightened by the way Oliver was acting.

Mosely called police and officers arrived several minutes later. Mosely says officers used a stun gun on Oliver at least four times.

Miami-Dade police say Oliver went into shock while he was in custody and was pronounced dead at a hospital later Friday morning.

Police spokesman Bobby Williams says the death is under investigation.
