A Spanish court is investigating three people close to Equatorial Guinea's President Teodoro Obiang Nguema Mbasogo over the treatment of the two Spaniards, a judicial source told AFP Tuesday.
Under the lamp are one of Obiang's sons, Carmelo Ovono Obiang, his security director Isaac Nguema Endo and Security Minister Nicolas Obama Nchama, the judicial source said.
According to police reports seen by El Pais, the three "repeatedly participated in torture sessions" to extract confessions from the four -- members of exiled opposition group, the Movement for the Liberation of Equatorial Guinea Third Republic.
The four were hung by their feet, causing their "blood vessels to explode", received electrical shocks and had boiling water thrown on their naked bodies, El Pais reported.
On the basis of these confessions, they received jail terms of between 60 and 90 years for allegedly taking part in an attempted coup against Obiang.
Aged 80, Obiang has ruled the oil-rich Equatorial Guinea with an iron fist since taking power in a coup in 1979, 11 years after independence from Spain.
Rights groups have often accused his government of arbitrary detentions and torture.
Vice President Teodoro Obiang Mangue - the son of Obiang, who is the world's longest-serving president, wrote on Twitter late Tuesday that former colonial power Spain was seeking to "tarnish" his country's reputation.
