Sirens, rubber traffic cones and even a lullaby - nothing could move an eight-foot alligator off the San Antonio's busy Loop 410 that sits on city's South Side. The reptile that apparently came from Mitchell Lake, just south of Loop 410, wandered onto the road Sunday morning causing a major gridlock on the highway for almost an hour.

Officer Albert Silva, who was the first to arrive at the scene of the traffic backup, said, "I don't remember any of this in the academy. As far as I know, there's no procedure on this other than: 'Don't get bit.'"

After Silva called for help with the giant lizard, at least 10 officers including a game warden reported to the scene who tried several methods to coax the gator to go back into a drainage leading to the lake.

Hoping to scare away the gator, the officers turned on sirens of their vehicles. But when that didn't work an officer sang the gator a lullaby over his police car loudspeaker, MySA.com reports.

Still not able to persuade it, officers then threw orange traffic cones at the gator, which it flung away like unwanted bait.

Finally, using some metal poles, the officers lent from passing by construction workers, they pushed the alligator back into the drainage.

State game warden David Chavez couldn't explain how the gator wandered onto the freeway, saying that the gators usually "keep to themselves. They don't go out looking for trouble."
