A Bonita Springs, Florida resident got a shock when he looked outside and saw an eight to nine foot long bull shark swimming in the backyard of his condo.

Richard Frey tells

: "I'm worried. I won't let our grandkids go in the water. Someone is going to be attacked here."

Residents say it's not the first time they've seen a shark so close to home. According to neighbors, the sharks return because someone keeps throwing bait into the water to lure the sharks in closer.

Now they're asking the city to get involved to prohibit fishing.
