A co-founder for Invisible Children was detained in Pacific Beach Thursday night for being drunk in public and masturbating, according to San Diego Police Department.

Jason Russell, 33, was allegedly found masturbating in public, vandalizing cars and possibly under the influence of something, according to Lt. Andra Brown. He was detained at the intersection of Ingraham Street and Riviera Road.

Brown said Russell was acting very strange.

Police said they received several calls yesterday at 11:30 a.m. of a man in various stages of undress, running through traffic and screaming. Police described him as "in his underwear."
