Update 12:43 p.m.:
The Los Angeles Fire Department announced that they are actively helping with the search for a teenage girl last seen being taken from the El Sereno Recreation Center Monday night.
According to the Los Angeles Times, over 100 police and fire personnel searched the area Tuesday.
No reports of a missing girl have been filed.
Police this morning are still searching for a teenage girl who may have been dragged up a hillside east of downtown Los Angeles and possibly kidnapped.
Police said witnesses reported seeing a man dragging a screaming girl by the hair into a brushy area near the El Sereno Recreation Center about 8 p.m. Monday.
The man also punched the girl, who was about 13 to 15 years old, and removed some of her clothing, police said.
Officers, aided by bloodhounds and helicopters, searched a 350-acre area. They found some leggings and tennis shoes, but not the girl.
NBC LA reports that investigators are still uncertain if there is a victim in the incident, but said they take every report seriously and will continue canvassing the area until they are certain the scene is clear.
"We believe that this really did occur – this is not a hoax or some incident that people misunderstood," said Lt. Andy Nieman told the station.
