A member of the Sudan People's Liberation Army (SPLM), Yasser Arman, has been arrested by the Sudan Military Council.

A spokesman for the SPLM, Mubarak Ardual, said gunmen said they were members of the security and intelligence services who arrived on pick-up cars. They surrounded Arman's home in Khartoum, smashed the surveillance cameras installed in the house, beat Arman and his assistant and took him to an unknown location.

For his part, said Osama Saeed, legal affairs of the bloc, "appeal Sudan" within which the SPLM, that the forces of rapid support and the security forces attacked members of the SPLM in their residence in Khartoum and arrested Yasser Arman.

Said held the military council responsible for the safety of Arman, stressing that he will inform the international community and international organizations of this "blatant" infringement.

Activist forces led by Mohammad Hamdan Humaidati, deputy chairman of the military junta, showed a crackdown in one of Khartoum's areas and spread on one of the main streets of the Sudanese capital.

Arman said on Tuesday that the dismantling of the sit-in "a crime will not go unpunished, and will not forgive our people," accusing the military council of the destruction of the political process altogether.

This comes in the context of a state of tension hovering over the country, after the disbanding of the sit-in of the General Command and the killing of dozens of protesters.

Arman is one of the most vocal opponents of the rule of former President Omar al-Bashir and returned to Sudan on May 26 after eight years of absence, despite a death sentence issued against him in 2014. The armed wing of the SPLM-North Sector is fighting the Sudanese army in Blue Nile and Southern Sudan Kordofan since 2011.

Arman arrived in Sudan to participate in talks with the military junta on the issues of the transition. On May 28, he announced on Facebook that he had received six letters from the head of the military council, Abd al-Fattah al-Barhan and his vice-president Hamidati, asking him to leave Sudan. Reject all these messages and commands. "

Britain's ambassador to Khartoum, Irfan Siddiqui, condemned Arman's arrest and wrote on Twitter: "This is outrageous ... we need to build confidence now, not more escalation"
