A suspect has been arrested in connection with the killing of journalist and gay rights activist Erick Martinez, whose body was found in May in eastern Honduras, a National Police spokesman said.

Eduardo Lopez, suspected of being one of the individuals involved in Martinez's murder, was arrested on Wednesday in Tegucigalpa's El Pedregal district, the National Police spokesman told Efe.

An arrest warrant was issued on Sept. 3 for Lopez in connection with the killing of Martinez, who worked with the Asociacion Kukulcan, a gay and lesbian organization, and founded the Diversity Resistance Movement, or MDR.

Lopez, a member of the Mara 18 street gang, also faces armed robbery charges.

Martinez's body was discovered on May 7 in Aldea Guasculile, located near Olancho province.

The journalist and gay rights activist ran for a seat in Congress from Francisco Morazan province on the ticket of the People's Refounding Force, or FRP, a movement of the Liberty and Refounding Party, or Libre, which emerged from the National People's Resistance Front, or FNRP, organized after the coup that ousted President Manuel Zelaya on June 28, 2009.

A total of 33 members of the media have been murdered in Honduras since 2003, but the killers have gone unpunished, the National Human Rights Commission says.

A man was sentenced on Tuesday to 28 years in prison for the April 2010 murder of reporter Jorge Orellana in the northern city of San Pedro Sula.

The sentence is the first handed down by a Honduran court in a case involving the killing of a journalist.

At least 20 members of the lesbian, gay, transgender and bisexual, or LGTB, community were murdered in the Central American country between 2010 and 2011, but no one has been punished for the killings, the Human Rights Commissioner's Office said. EFE
