SAN DIEGO (AP) -- A co-founder of the Invisible Children charity behind the "Kony 2012" video was detained by San Diego police and hospitalized after running through streets in his underwear and acting irrationally.
Police Lt. Andra Brown tells NBC San Diego that Jason Russell was behaving strangely Thursday, screaming, yelling and interfering with traffic while in various states of undress.
Brown says police decided he needed medical attention.
Invisible Children CEO Ben Keesey says Russell was hospitalized for exhaustion, dehydration and malnutrition. Without details, Keesey says recent severe emotional toll manifested itself in "an unfortunate" incident.
Russell narrates the "Kony 2012" video about wanted African warlord Joseph Kony which became an Internet sensation this month.
The video has brought heavy scrutiny of Invisible Children's strategy and financial practices.
