LOS ANGELES, Calif. (KTLA) -- Authorities are investigating a kidnapping-for-ransom case involving a 64-year-old grandfather who says he was abducted at gunpoint in Vermont Square and held captive for several hours.

The man says he was playing with his granddaughter outside a home in the 1800 block of West 47th Street, near St. Andrews Place around 8:30 p.m. Tuesday when he was approached by two armed men in a green van.

The men allegedly forced the grandfather into the vehicle at gunpoint and drove him around while calling his family, demanding ransom.

The suspects were said to have requested as much as $100,000.

The grandfather was dropped off at a McDonald's restaurant in Lynwood around 12:30 a.m. Wednesday.

The man was treated for an ankle injury and interviewed by police.

No further details have been released.
