WASHINGTON (Sinclair Broadcast Group) -- Authorities in Los Angeles are looking for a young boy who reportedly fell into a drainage ditch in Griffith Park.
NBC 4 reports the Los Angeles Fire Department has been on the scene since 4:30 p.m. PST. At least 100 firefighters are on the scene conducting an air and ground search. Authorities say the boy is 5'7'' and 180 pounds. His cousin called police to make them aware of what was going on.
ABC 7 reports the drainage ditch is 13 feet wide and two feet deep.
LAPD says the boy was jumping on a wooden plank when the plank fell causing the boy to fall into the drain. The water is flowing at 10 to 15 miles per hour.
The fire department is looking at the LA River as well as a water reclamation plant in Glendale, Calif. to see if they'll be able to find the boy there.
Officials have not been able to find the boy, a spokesperson for the department tells KNBC.
This is a developing story.
