Gyllenhaal on scene of shooting
Jake Gyllenhaal and Michael Pena got a front row seat to LA gang violence.
The actors, who were riding along with police on patrol in South LA, were on the scene of a gang shooting late on Wednesday.
The pair are researching police work for their roles in the forthcoming movie End Of Watch.
Sgt Angela McGee says a gang member shot a rival, who is hospitalised with a grazing bullet wounds above his lip and on an arm. Two suspects walked away and there are no arrests.
She says the actors were on patrol with 77th Street Station officers. KTTV Fox 11 video shows the actors talking while officers investigate nearby.
End Of Watch is a drama that focuses on the partnership of two police officers.
