“Where is Luis Carlos?” Image of the public online campaign shared by Provea. In the image they indicate the last time he had been contacted and the last time he tweeted.

On the evening of March 11, political commentator Naky Soto and wife of Venezuelan journalist and media activist Luis Carlos Diaz tweeted that he had been missing for five hours.

[Update] The Union of Press Workers (in Spanish, the SNTP) reported that Luis Carlos had been detained by the Bolivarian Intelligence Forces (SEBIN):

#URGENTE | Comision del Sebin confirma que el periodista Luis Carlos Diaz está detenido en ese organismo policial apuntan con armas a directivos a @mruizsilvera, @LuzMelyReyes, @LilaVanorio y a @FedericoBlackB #DondeEstaLuisCarlos #12Mar

URGENT A Sebin commission confirms that journalist Luis Carlos Díaz has been detained by that police organism. They pointed their weapons at journalist [and members of the Press Union] Marco Ruiz, Luz Mely Reyes and Federico Black.

Hours before, Soto had tweeted that Luis Carlos Díaz had been missing for five hours:

Estimados: perdí contacto con @LuisCarlos a las 5:30 de la tarde, cuando me dijo que venía a casa a descansar porque esta noche haría una jornada especial en @Unionradionet desde las 10:00 pm hasta las 5:00 am#DóndeEstáLuisCarlos

— Naky Soto (@Naky) 12 de marzo de 2019

Dear everyone: I lost contact with @LuisCarlos at 5:30 this afternoon, when he told me he was coming home to rest because he was going to do a special broadcast at @Unionradionet from 10:00 pm to 5:00 am #DóndeEstáLuisCarlos

.@LuisCarlos anda en bicicleta, pero desde las 5:30 pm no sé nada sobre él y:
– no está en la emisora
– no está en casa
– no ha tuiteado
– no contesta llamadas
– no contesta SMS ni mensajes en WhatsApp#DóndeEstáLuisCarlos

— Naky Soto (@Naky) 12 de marzo de 2019

@LuisCarlos is on his bike, but since 5:30 I've heard nothing from him and:
– he's not at the radio station
– he's not at home
– he hasn't tweeted
– he isn't answering calls
– he isn't answering SMS or WhatsApp messages
#DóndeEstáLuisCarlos

[Update] As members of SEBIN searched Diaz's and Soto's home, Luz Mely Reyes reported live from the scene. The SNTP also reported the incident:

#URGENTE | A esta hora, 2:30 am, comisión del Sebin llega a la residencia del periodista y activista de Ddhh, Luis Carlos Díaz, desaparecido desde las 5:30 pm #DondEstaLuisCarlos #12Mar

— SNTP (@sntpvenezuela) March 12, 2019

URGENT At this time, 3:30 am, a commission from the Intelligence Forces arrives to journalist and human rights activist Luis Carlos Díaz's home, missing since 5:30 pm #WhereIsLuisCarlos

Other human rights and freedom of speech organizations joined the campaign through #DondeEstaLuisCarlos (Where is Luis Carlos?) which is, at the moment, a trending topic in Venezuela's twittosphere.

Díaz is a journalist and a human rights and freedom of speech advocate who is well known and highly appreciated in Venezuela and abroad for his commentary and criticism of the government of Nicolas Maduro. He has long worked with Soto producing web-based video and radio programs focused on politics and human rights in Venezuela. He has also worked as an educator and promoter of the creation of citizen media spaces and independent media projects. Díaz has also been part of the Global Voices community for more than a decade.

Para mí Luis Carlos es una pequeña lumbrera de información y redes en esta Venezuela tan caótica que nos tocó. Él ha logrado establecer vínculos con la sociedad (desde la crítica hasta espacios culturales) #DóndeEstáLuisCarlos

— Verónica A. Ifigenia (@verocosmica) March 12, 2019

To me, Luis Carlos is a brilliant person, well versed in information and networks in this chaotic Venezuela of ours. He has been able to make links with society (from criticism to cultural spaces) #WhereIsLuisCarlos.

Just a few days prior to his disappearance, the state-affiliated media program Con el Mazo Dando showed a video clip of a recent broadcast of Diaz. The program's host, politician Diosdado Cabello, insinuated that Diaz had helped to orchestrate the nationwide power outage that had Venezuelans living in the dark for more than 24 hours on March 7 and 8.

There is no evidence to support this.

#DenunciaEP | Desde las 5:30 pm se desconoce el paradero del periodista Luis Carlos Díaz (@LuisCarlos). Hace varios días fue acusado de “influencer fascistoide” a través de la cuenta de Twitter de “Con el mazo dando”. #10Mar#DóndeEstáLuisCarlos

— Espacio Público (@espaciopublico) 12 de marzo de 2019

#DenounceEP Since 5:30 pm the whereabouts of journalist Luis Carlos Díaz are unknown. He was accused to be a “fascist-like influencer” through the Twitter account of “Con el mazo dando”.

Our friend @LuisCarlos is one of the most visible faces of dissident journalism in Venezuela. A few days ago, Diosdado's #conelmazodando targeted LC with a tinfoil hat propaganda campaign linking him to “the US planned” nationwide blackout. #DóndeEstáLuisCarlos

As time without solid information continues to pass, the SNTP joined the campaign that started the search at the headquarters of the Intelligence Service (SEBIN):

#AHORA | Siete horas han pasado desde que desapareció Luis Carlos Diaz, periodista de Unión Radio Noticias y activista de Ddhh. Estamos ahora en el Sebin del Helicoide y niegan tenerlo #DondeEstáLuisCarlos #12Mar

— SNTP (@sntpvenezuela) March 12, 2019

It's been been seven hours since Luis Carlos Díaz has gone missing. [Díaz] is a journalist for Unión Radio Noticias and he's a human rights activist. We're at the SEBIN headquarters and they deny having him [in custody there] #WhereIsLuisCarlos

[Update: they later confirmed Diaz was in custody]

Journalist Vladimir Villegas denounced that he had been detained by government forces:

Se nos informa que el periodista Luis Carlos Diaz, de @Unionradionet, ha sido detenido por cuerpos de seguridad del Estado. Expresamos nuestra preocupación por su integridad física . Exigimos información cierta sobre su paradero y respeto a sus derecho humanos.

— Vladimir Villegas (@Vladi_VillegasP) March 12, 2019

We've been informed that @Unionradionet journalist Luis Carlos Díaz, has been detained by State's security forces. We express our concern for his physical integrity. We demand any information of his whereabouts and respect for his human rights.
