KEY WEST, Fla. (AP) _ Even police chases are different in the laid-back Keys.

Officers were called to the Ocean Key House marina early Sunday because a 55-foot cruiser was bashing into other boats.

A man appeared on the bridge of the cruiser Fireball, saw police and dove into the water.

Usually, that's when police shout ``Freeze!''

But this is Key West.

They yelled ``Sharks!''

The man swam ashore _ rapidly.

Jon Davison, 34, of Titusville, was booked on charges of grand theft and burglary, The Miami Herald reported today.
