EL CAJON, Calif. - Police in El Cajon received dozens of phone calls after people spotted strange lights floating in the sky.

Some people gathered in parking lots, looking to sky for answers. The lights were thousands of feet in the air and did not move or sway.

"I really don't think that it’s attracted to the ground because it's pretty high up there and it's not moving at all," said El Cajon resident Michael Kayler. "There's got to be wind current up there."

It turns out that a neighbor named Todd had spent $300 on balloons, helium and lights. He had the entire contraption on fishing line. The lights were more than 4,000 feet in the air.

"[It's] a 'TFO'… Todd's flying object," he said.

It is unclear if Todd will get in the trouble for the lights. He said he put them up all in good fun.
